7 blinks means unit is locked out it will stay locked out for one hour then try to light again it will try two times before lock out. Possible causes. Low gas pressure, Faulty gas valve, Faulty hot surface ignition or burner problem may cause this. Most common is Hot surface igniter.

A constant red light (not blinking) indicates that the thermostat is not calling for heat. Of course you know it is but just to be safe, jump out R and W on the board. If it continues to do the same as you indicated, replace the board.

SOURCE: goodman gmp075-3 led blinks 5 times

I Also have the same and other problems with my furnace model # GDS80703AXBB. First the LED kept blinking 4 times and I too jumped the primary limit, that didn't kelp. After several attemps I moved the wires going to the circut board and everything starting working again. After a week It stopped working again, so I pulled the plug out of the circut board checked all wires for for a bad connection plugged it back in. Now the LED blinks 6 times again I move the wires. Then the LED blinks 3 times. Then the transformer burns out. I have burned out 2 transformers and I have ordered a new circut board.

I have a goodman GMP075-3 that won't turn on. I think it is the pressure switch since I do not have a vent blockage. What is a venter and where can I find it??

SOURCE: Amana Air Command 80 SSE gas furnace will not stay running

In the path of the flame on the last burner that starts, there will be a small rod. That rod is the flame sensor. Take a scrub pad and polish it. Also check the electrical connection that goes back to the circuit board. Disconnect any ground wire from the circuit board to furnace cabinet, sand it and replace it.

Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

Turned my furnace off while going away on vacation. When I came back, the furnace would not turn back on. Lockout light is blinking.


with some thermostats you must cycle the power after a lockout relay energizes, so turn the stat off and back on and then check operations to see what caused it to lockout, often the lockouts are on low and hi pressure safeties, so you may have a refrigerant charge problem

Kenmore furnace mdl BGU100168 status light indicates ignition lockout. How to correct.


Can you please verify the furnace mode, nothing comes out with the BGU100168 model #. Is it an oil or gas furnace? Was it bought at Sears?
In the mean time you can try cleaning the filter, with a piece of emery or sand paper sand clean the flame sensor (thermocouple) in front of the pilot light (if applicable). Reset the unit by disconnecting the power for 5 min. and tuning it back on.
Keep me posted!!

My central heating is on lockout and the burner is with red light


A sampling of various codes on a furnace

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your Goodman furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

Furnace will start and sequence fine run for five minutes or so then the flame cuts out....miller type furnace put a new board in last year so now it cycles three times and goes into soft lockout.....


Clean the flame sensor.

If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Sounds as though your issue lies within the flame sensor.

The flame sensor senses that there is flame present once there is a call for heat. It sends its signal back the board or ICM and the furnace operates as normal. If no signal is sent, then the furnace automatically shuts down as a safety procedure. The furnace will attempt to light several times before shutting down on a fault code or lockout.


The number 1 reason for flame sensors to fail is they are dirty. Check the sensor for dirt build-up. Clean the sensor with a damp rag or a scratch pad. Inspect the grommets for crackings. Also check and clean all grounds. If this doesn't work, you will need to replace the sensor or call for a service technician to ensure the sensor is the only issue at hand.

My rheem cri II furnace will not work unless I turn the gas valve knob from on to off and back. The green led light is blinking then solid when I reset knob. Any ideas?


The green light is flashing an error code. When you turn the knob off and back on you are resetting the safety. Look for the number of blinks in a row. Then find the legend for codes on gas valve or on furnace. When is the last time you changed the air filter? A dirty filter can cause this problem.

Gas valve lockout


It means that the furnace isn't igniting and for safety the control board is preventing the gas valve from opening. Turn off the power to the furnace for a few seconds then observe what the furnace does in heat mode. Some furnaces will run the blower for a minute after you power it back up. After that see if the furnace tries to come on. If you are still getting the code then one of you high temp limit or roll out switches has tripped. Now is the time for a service tech. Make sure that you check you filter and air flow too. Low air flow means the furnace may be over heating.
The other thing is the hot surface igniter. Look closely at it with the power off. Do you see a white spot on the element or a crack. If so the HSI is bad. It's an easy replacement but DO NOT touch the carbon element with your fingers and be very careful handling it as it is EXTREMELY fragile.
