If you will look on the cover panel there should be a list of fault codes. The blinking LED light is giving an indication of the fault that has the unit shut down. Depending on what the fault is, you may need to have a qualified hvac technician come in and check it out. My Goodman only lists up to 7 flashes on its chart inside the door panel. My initial problem was a lockout flash code due to 3 failed start attempts. It will reset and try again after an hour or you can switch the furnace power switch a regular looking house switch alongside the furnace off and then on again after about 30 seconds.

The start sequence occurred and the ignitor lit but no gas would come from the valve to ignite. I put 24 volts to the valve to test it and it worked fine so I manually ran it this way while I went to get a new circuit board. Everything else seemed to be ok. I figured a relay had worn out on the old board since the new board did operate the gas valve ok after it was installed. It worked fine but it would now flash 8 times on occasion and the furnace had to be reset to clear the problem again for a while.

It might work good for a day or 2. I did not have the c terminal bonded to ground initially which the new board indicated is a cause for the 8 flashes. This however did not eliminate the problem. The trouble chart also indicates a faulty thermostat to be the cause. On several occasions a reset would not even get it to work since the flame would only burn for about a half second and go out and that was it. A flame sensor would not even be able to detect a flame that fast to keep the gas valve going so a dirty or faulty sensor could not be the issue on an instant flameout.

I disconnected the wall thermostat and connected the red and white wires together and the flame now continued to burn instead of flashing out. I decided to replace the thermostat which I had initially believed to be working correctly with a different make in case it was somehow just incompatible and there have been no issues anymore. The system would work fine but there had to be an issue with the thermostat where it apparently put in a temporary call to the furnace for heat but would not maintain that call so the furnace would start to go through the start sequence but could no longer follow through with the opening of the gas valve.

I have a feeling the original circuit board I replaced is still good and will be kept for a spare since I never did jumper the control board to wire up a manual heat call without the thermostat attached.

I never mentioned that the first thing I ever did was test to confirm the batteries had been good and then replace them with new ones after that but the thermostat still had random issues operating the furnace properly. In addition to the above poster. The light is the fault code. You need to remove the furnace panel from the furnace.

It blows cold air. I have to turn it off for a few minutes and when I turn it back it on it will ignite and I will get warm air. When I turn it back on the red light blinks 7 times, goes dark, and blinks 7 times again before staying a steady red.

The same thing happened last year and the guy told us the filter was dirty and it was nothing.

Diagnostic Code Identification System

In addition to the question of what the 7 blinks mean, I am wondering if companies manufacture their furnaces this way so that you have to place a service call at least once a year? Hi Cesarina. Are you sure the last tech said it was a dirty filter, or was it a dirty flame senser? Either way, it sure sounds like a dirty flame senser this time.

Very common, and easy to fix yourself. I would suggest having a tech in one more time, but this time be there to watch. Ask him what he is doing, and how to clean the flame senser. A good tech will be happy to show you the basics of the furnace. As far as the manufacturer making it so you have to have a service call every year, no. The diagnostics light is actually to make trouble shooting easier. If you have the install manual, or homeowners manual, you can read through it and actually find how to fix many problems yourself.

If you know where the flame senser is located, remove it, clean it with steel wool or fine sand paper and put it back in. This should get you back in steady heat. Not your question? Ask your question View similar questions.

Trane furnace xr80 troubleshooting red blinks [ 4 Answers ] Tranexr80 lights flash 5 timesWhen the pressure switch on your Goodman furnace is open, and power cannot pass through, the furnace starts the inducer to begin the heating process. If the pressure switch is closed, where power can pass through, the IFC will stop the process and try again.

In the meantime, it will go into lockout mode. The pressure switch is located to the top left of the inducer the big black thing when you pull the cover from your Goodman furnace.

Your Goodman furnace will go into lockout mode and try to turn on again if something happens during the inducing process to halt it. Some of the things that might be happening are: the pressure switch is open, a short in the pressure switch circuit, blockages in the flue or many other reasons. In Goodman furnaces, the relay switches for the fan there are two of them are integrated into the circuit board.

If the blower keeps running, you may have to replace the circuit board. If this is the case, it could be several things, depending upon the error code that you are getting. If the burner does not ignite, gas could be not reaching the burner, the flame may not be lighting or the vent motor may not be running. It could also be the pressure switch, or blockage in the vent.

This means the furnace locked itself out because it tried to ignite three times and could not do so. You can solve this by cutting power to your Goodman furnace for 30 seconds, or by lowering your thermostat to what it was before you turned it up and then try to turn it up again.

Your furnace will automatically try again after an hour of lockout. This means that the blower is not working, or the pressure switch circuit has a short in it. You may have to repair the short circuit or replace the pressure switch.

Make sure you cut power to your furnace before beginning any work. The pressure switch circuit is open or the induced draft blower is going. Check the pressure switch hose for blockages and ensure it is connected properly. Check the flue for blockages and look for loose wiring.

You also might have a blocked filter. Check the wiring, clean the filters and make sure the flue is open and clear. Five LED flashes mean that there is a flame before the thermostat has called for heat. This is probably because the gas valve closed to slowly or some other reason that caused the burner flame to stay lit longer than it should.

This means there is a low flame. Probably from low gas pressure or a coated flame sensor. Adjust the gas pressure after turning off the power. This means that there is a problem with the igniter circuit. The igniter could be bad or just not connected properly.
