All of the burners should light. Could be a dirty flame runner. I recommend that you get a good clean and check.. Burners, flame runner, flame sensor should all be cleaned. If this does not solve your problem than the gas pressure needs to be checked.
Good luck....

Hi, you will need to replace this thermostat as the circuitry is faulty and keeping the strips energized. The only way to check would be to pull cover from stat and expose stat wires. Power off first. Disconnect the 24 volt hot wire, red and they should shut right off. If so get a new stat. If you need further help, please contact me. Merry Christmas.

We need to change the heat exchanger for my Goodman Heat Furnace model no.-GMP 075-3


Not an easy task! Take many pictures as well as draw out and mark which wire went where. You will have to remove everything from inside the cabinet to get to the heat exchanger. It may be easier to replace the furnace. If you are paying a professional to do the exchange, figure three hours if they have done it before, if not figure 5 to 6.

I can't find any info on my Goodman furnace.It's a GMP and the model number on the front of it doesn't match any goodman model numbers G2FD036S17A......I'm lost


Take the top panel off and on the inside of the left side of furnace as you are facing it should have a nameplate rating.

The nameplate rating should have the model number and serial number of the actual unit that you have.
It will list BTUS/Electrical Amps.

How to change fan speed on a goodman gmp 100-3 furnace


Usually you can find the control board on the lower part of the furnace. Turn the power off and remove the
doors. This board is usually located directly in front of the blower motor.

On the control board locate the terminals marked heat/cool/park and Park Lets say the Heat Terminal
has a red wire attached to it and you want a higher
speed.

Red is uasually low speed, remover the red wire from
heat terminal and exchange it with a wire attached to
a terminal lab eled park. Black is usually high spped

My gmp series heater comes on for 30 seconds to purge exhaust and goes off for 2 seconds and starts over red light flashes constantly gas valve never opens igniter doesnt heat up


Sounds to me like your pressure switch is bad or the hose has a hole in it. If the pressure switch does not close, the unit will start. It will try again until it goes into lock out. normaly three times.

I don't know where you are located, but there is a Goodman distributor in Sacramento, CA. Also in Ontario CA. They are a distributor so they may be able to help you or tell where to find someone who will help. Goodman is also known as GMC or Janitrol.
