This is causing the high-stage draft blower to run. The house breaker is fine. Do you know for sure that the unit was converted to LP? You need to monitor the frequency of the flashes and their speed. But the main problem with such a furnace is that the unit will remain energized, even when it is turned off. It may be turned off for the season, a plug may have come loose or the circuit is tripped. There are no blockages in our flu, I replaced the filter (just in case), cleaned the flame sensor (for good measure), and removed the pressure switch to see if it was obstructed or visibly stuck in some way (9300-V-0.55-DEACT-N/O-VS). A code like this means that there is a flame detected without the gas valve turned on. Any thoughts? I've replaced the thermostat (which only has a red and white wire connected to it) and the flame sensor. There are just too many possibilities to narrow it down based on this. Thank you Mark! Birds and other small animals have been known to take up residence in flues when it's particularly cold. This is something that becomes apparent early in the heating season. Do you have a suggestion? The evap pump has a solid green light HVAC Technician: Gaztech1 Evap pump is added to the installation, not part of furnace If led #1 is steady on, it says the control circuit board is defective. Since it's pretty cheap, it might be worth trying before saying it's the board. Cj - I'm sorry but there just isn't enough here for me to offer any real sound advice. Usually, this fades over time and isnt something to worry about! My furnace will kick in and get it to the desired temperature and it will click and stop blowing hot air but it is still blowing. Slow or Fast. What does a solid red light on a Goodman furnace mean? Check your breaker and service switch as well as the little 3-amp fuse on the board. I've written other articles that may help you narrow down your problem and perhaps make the repair. If you do, then the problem is either the gas valve not opening or the gas is off or potentially there is air in the line and it may need bled out. For someone who is familiar with taking things apart and putting them back together I'd say yes, it's a pretty easy task. To troubleshoot this device, follow the instruction . My furnace blower is running but not blowing out heat, my thermostat is off, what do I do? No power to our Coleman Forced Air Furnace. Fan constantly runs but nothing else happens. The problem is typically a dirty air filter, the wrong-sized ductwork, the wrong blower speed setting, or a bad blower motor. Since the blower is kicking on immediately, something has failed. I do not have enough info to recommend you do anything with those wires other than what they're intended for. If the inside seems dirty, use a soft brush to gently clean the thermostat. You'll be a very informed customer when they come knocking. Furnace Filter Airflow What You Need To Know? I think it's a little high but I'm in the "Heartland" so perhaps that's reasonable for the west coast. Also, check outside to make sure the ends of the pipes are clear and not iced over. The problem is, most likely, with the thermostat and not the actual heating unit. Answer: The thermocouple confirms that the pilot is and stays lit. later. If I disconnect the a/c wires the furnace works fine again, Thermostat seems to be working fine. Swap it out for a clean one to solve the problem and prevent overheating! Perhaps a burnt out heating element? If have power coming out of the on off switch on my furnace and the 5 amp fuse is still good, why wont the green indicator light come on? Answer: While water is difficult to track the source/problem via the internet, I can say that a 5-year-old Lennox may well still have a parts warranty so if you get a tech you might only have to pay labor. BE SAFE! If not, it's the board and if yes, it's the sparker itself. If the fire is on, the air cannot be cold. Checking for obstruction in exhaust pipe and running shop vac through each end, cleaning out condense tubes I still had two flashes. These are where I would start. If the first LED light is Off, and the second is exhibiting a slow flash, theres a problem with the pressure switch that usually cant be repaired. The roll-out switch is jammed while being open. thank you. Question: How do you know when your circuit board on a forced air HVAC unit is defective? I did remove the flame sensor and cleaned it but I fear I may have cleaned it too much by way of over use of sand paper. Simply pull the fuse off the board and look to see if the link inside is burned and/or broken. Temperature Not Match The Thermostat Setting? Any thoughts? Question: My furnace doesn't seem to be getting any gas. Hi i have a goodman its flashing red light. RAur - You're welcome. When it comes on, it makes a clicking noise that sounds like it is coming from inside the junction box, but it turns off fine when it reaches the desired temperature. Answer: You may have an issue with the pressure switch. The ignitor does not appear to light whatsoever, I hear no clicking, smell no gas. We start with the simplest problems and then test for more difficult issues. Answer: You test to see that the spark igniter is getting proper voltage from the board. Its unknown what may cause this. I have an amana furnace and its flashing a red light 6 times. Here are the blinking red light error codes of a York and Luxaire furnace and what each one means. Question: I have a furnace with the spark ignitor and the pilot does not ignite. Cricut machine does not cut through my material. In a lot of cases, a unit with a reversed polarity will continue to work. Five blinking red lights usually signal that a rollout switch or an auxiliary limit switch is open. A York furnace will blink red once when no power is provided to the gas valve, and a fire is still present. Your system is currently locked out of its normal operation or ability to function. This code relates that your furnace's limit switch is stuck while being open. Question: My Comformaker furnace is showing a four flash code. Question: I have a 2003 Lennox gas fired, forced air furnace. Your furnace is functioning normally, and there is a call for heat from your thermostat. When I turn it on, it will light, heat, and blow hot air until it hits temperature and shuts off. I have to clean mine every year. Before you call out the pros, why not take a shot at fixing that furnace yourself? Your unit might have low gas pressure. Could this be a bad board? Here are a few other things that you can do: At times, the blockages might be impossible to get rid of. However, i am able to get the fan and heat going when i manually turn off and then turn on the furnace's electrical switch. I also replaced the pressure switch with the original manufacturer part. Any idea why this would happen? DO NOT try to substitute the fuse with one of another amp rating. Your furnace has been locked out. If, for some reason, you would have to install a new pressure switch, make sure to install the component in a vertical position. The LED on the board had two flashes which indicated "inducer motor on with pressure switch open." 5. Pressure switch is where I would start my assessment. Nothing! Why Does My Furnace Filter Get Dirty So Quickly. Common causes are a bad blower motor or faulty blower wheel. Different problems range from faulty wiring and carbon build-up on furnace parts to reversed power polarity. I light the pilot light, and my furnace will come on for a few minutes, but then the flame dies. Some Rheem models particularly newer furnaces have an integrated furnace control inside them that flashes a warning LED light when there is a problem with operation. It was working fine and then it blew the 3amp fuse on the control board. Two LED flashes. What could be the cause of this? Shirley - I can't offer any advice based on this. Goodman furnaces have a display panel with a built-in trouble-code that uses LED lights to show the homeowner that there is a malfunction of some sort. This is a major fire hazard.

Answer: It may have been a fluke if it's not a regular occurrence. A solid red light might mean two things that the board is normal and its simply waiting for a heat call or that the burner is running but the unit is not getting a call for heat. Mrs. Klann - While I can't say what's causing this I can say that the unit should be shutting off then because if the flames run without the blower it will overheat and shutdown. What could be the problem? What would cause this? Dave - I answered the other question but here there are a lot of moving parts and I'm not sure what you're dealing with. Answer: I do not know what the four flash code means as the codes vary per brand. I have power going to the circuit board, but there seems to be no power going to the blower motor or anywhere else. Question: Why has the furnace started making a knocking noise and smelling like a hair dryer? This might have happened because there were too many ignition attempts. Since doing this the furnace has run fine. When both lights are blinking fast, either the ignitor is broken, or the system has low voltage. It could be a bad connection, or a problem with the circuit board or stat. These usually fail or they don'tthey don't usually act erratically unless they need cleaned. The visit and the flame sensor together cost me ~$300/-. Most of their codes overlap, with a few exceptions. Question: There is power going to the furnace, but the Indicator light not working.

Answer: I hope you're using something besides your hand to do that, but it sounds like the capacitor if that's what's happening. Carrier. In my experience, a solid red means the unit has power and is awaiting command. The furnace will once again enter lockout mode for 60 minutes. Try this for me.. turn power to furnace off and on 4-5 times within 30 seconds. We have a Coleman electric furnace and it clicks like its turning on but its not actually kicking on to blow airand it smells like something is burning when its trying to click on. Amana Furnace Error Codes Amana HVAC systems are also highly-dependable and efficient. Overvoltage limit of the board is approx. If your York furnace blinks red 6 times, the modulating gas valve is experiencing a failure. Most alarm system smoke detectors need to be reset from the control panel. If I manually light (light paper and put in front of the pilot) the burners will light and the furnace will run for 20 minutes and then shut off before reaching the set temperature. Please get a 2nd opinion. TD - I really can't say from here. Hello, my furnace was coming on and cycling about 5or 10 sec. Sometimes, the little red light indicates an open pressure switch, which often means a flue/chimney blockage. Answer: In my world "control" would be the circuit board (control board) or ignition module (ignition control). Keep in mind this is just a process, not a diagnosis. Answer: Yes, it could very well be. My furnace is switched to on gas is on now the red light on the board is not on the wires on the furnace are hot as they sparked white hot but no red light it isn't turning on, or even trying to run. This article is accurate and true to the best of the authors knowledge. 4 flashes what does it mean. I'm at a loss. Should this blink-code occur, take a look at the high-limit switch (similar to a pressure relief valve on an air compressor). Maybe a limit? The red blinking light can be an indicator of a number of problems or malfunctions with your heating system, so it is best to act fast if this happens. Question: My furnace igniter glows hot, but the flames fail to ignite. Rich - The pressure switch clicking when you blow/suck on the tube doesn't mean it is working properly. Turn the valve to OFF and wait for 5 minutes; if you smell gas, call the gas company right away.

Answer: If the high limit switch has been tripped then yes, the blower would run until the temperature drops to the allowable range and then try to fire again. Find the gas valve (it's usually located on the back of the furnace). I have a Honeywell pilot valve question, since it started recently having trouble getting the pilot to light and it continually got worse to where it will not light now. One thing I can say is that if the unit was registered, then you should still be under warranty. Question: My electric bill doubled this month. This light blinks a sort of Morse code, a number that corresponds to a chart located somewhere on the furnace. Hi, last February I had a Heat exchanger replaced in my Miller Propane Furnace. The most common blink codes are: LED light #1: Slow Blinking | LED light #2: Slow Blinking, LED light #1: Fast Blinking | LED light #2: Fast Blinking, LED light #1: Slow Blinking | LED light #2: Solid, LED light #1: Off | LED light #2: Slow Blinking, LED light #1: Alternating Slow Blinking | LED light #2: Alternating Slow Blinking, LED light #1: Alternating Fast Blinking | LED light #2: Alternating Fast Blinking, LED light #1: Slow Blinking | LED light #2: Off, LED light #1: Solid | LED light #2: Slow Blinking, LED light #1: Blink, Blink, Off | LED light #2: Blink, Off, Blink, LED light #1: Fast Blinking | LED light #2: Slow Blinking, LED light #1: Slow Blinking | LED light #2: Fast Blinking. I have identified the simple fixes above, and if you still haven't diagnosed the problem, messing around any more could compound both the problem and the expense. Question: Why would a thermocouple need to be replaced if the furnace pilot ignites? Read: Furnace Filter Airflow What You Need To Know? it just shuts back down. Bad wire? Manually recycling the power was helping, but with that i was was getting lucky with it working at times and not at other times. Here is everything that you need to know. Find the furnaces front panel and remove the screws. A blinking red light on your furnace indicates a technical error specified by one of its many codes.
