Question about Goodman GMS90703BXA Heater

1 Answer

Hi, I have a GMP furnace that's probably 13 years old. It recently was intermittently not coming on and we thought it was the thermostat so we removed the programmable and put the old thermostat back. It worked for a while and now it won't go on, again. Nothing. Nada. When we turn it on, the furnace does absolutely nothing. Anybody out there familiar with GMP's enough to guess what the typical failure mode would be?

Fan will not cut off


Janet, the problem most likely is not in the thermostat. It is probably the fan relay on the circuit board in the furnace. Some furnaces have an individual fan control board, some furnaces have all the controls integrated within one control board. If your furnace is 20 years old or older, it could be the fan/limit control because at that time all furnaces did not come with a control board. If it is much older than 20 years, it is much more likely a stuck fan/limit.

My Coleman propane furnace kicks out once and a wile and flashes a 10 flash code (gas flow with no call for heat) what need to be fixed the furnace is only 1 year old.


This sounds like you have an intermittent main board problem. It may be turning on you furnace when the thermostat is not calling for heat. It also could be a short in your low voltage(thermostat wire) going to your furnace. Either way you need to have it checked. It's under a year it should still be under warranty.

Goodman furnace\ blower comes on,unasked


Sounds like the fan switch on the furnace is set to low. Turn power off to furnace, take door off of furnace look for a fan switch, it may be a fan - limit together. The limit settings should be approximately 160° to 200°, and the fan settings should be about 100° to 140° set it to 120° it it's already set there then you probably need to replace it.

This sounds Programmable Thernostat related. Do you have a new thermostat? And are you familiar with how to overide the progammed feature, such as set on manual or push the hold button. Thermostats are generic so you could have any make or model. If you feel confident you could install a different Thermostat. You just need to unplug and then mark the wires accordingly- there should be 4 wires. There are a couple other things that could be happening is your unit may not be lighting properly. If you go to the unit when its not working I believe your unit has a blinking light on the circuit board of the unit that will tell you what problem is occuring. The code is affixed to the furnace panel I believe. There are so many safetys on your unit, the best way to troubleshoot is that tattletale light. Good Luck

Furnace runs OK, but blower runs again a few seconds later


Could be a defective thermostat in the plenum.
When a gas furnace shuts down the fan(blower) will run until the plenum cools to the safe range. Usually 1 and 1/2 minutes.
Intermittent operation is a defective thermostat or relay.

However - the problem is probably not with your thermostat but with your furnace. It is most likely a dirty flame sensor - a maintenance issue. If you have not had your furnace serviced recently (more than 1 year) that is where you should start. Modern furnaces require regular maintenance.

Heat temperature issues with Goodman GMP 100-4 furnace


69,000 btuh is adequate for a 12-1400 square foot house.
Otherwise, your thermostat simply tells the furnace to cycle on/off.
If it calls for heat and does not come on, the problem is with switches and relays within the furnace.
Your setting the temp higher only causes the other parts to keep trying until they finally light and heat.
This is based on your information saying it will cycle on and blow cool air--not hot air.
You will have several temperature variations from floor to ceiling.
You probably have ceiling vents as well.
You need a technician to verify the rollout switches, fan relay, inducer fan etc. if the furnace is not firing everytime you call for heat.

My honey well thermostat keep clicking and I can't program it


If you have a programmable thermostat and it is a couple of years old you will probably have to install a new one. What kind of thermostat do you have? You can turn power off to furnace and then take thermostat off wall and take wires marked r & w and connect them together your heat should come on when you turn power back on. If not you could have blown the 5 amp fuse inside furnace. I would check the fuse inside of furnace. If you take panels off front of furnace you should find a controll board inside that runs furnace.If you have anymore question just reply back to me
