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?

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 GMP Furnace problem. Original problem is


Good one! Is the flame getting to the flame sensor within the few seconds? Maybe a good cleaning of the burners or flame tray would help. 1.3 ma is enough for the flame rod to tell the board to stay on. Re-do all the ground connections both at the board and furnace cabinet to be safe. Check the polarity of the power going to the furnace. What are the chances the second board is bad?

Thermostat not turning on furnace.


Hi, You need to go to the furnace to see if you have lost the 24 volt supply, the transformer. If you have a circuit board, see if it has a 3 to 5 amp fuse plugged into it that is blown. This will kill power to stat causing nothing to work. Let me no what you find and we can go from there.

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.

Hello I have a GMP 150 installed last year. The furnace works fine, but after a day or so, it does not react to the thermostat. so the led light of the thermostat is solid red, but the GMP 150 does not...


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

The Thermostat Wizard is an interactive tool that will guide you through wiring and troubleshooting your thermostat, as well as programming it to the most comfortable settings for you and your family. Simply answer the questions from the Thermostat Wizard to correctly connect, troubleshoot and/or program your Honeywell Thermostat. You can even print the instructions and bring them right to the thermostat to help make things easier.

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.

Blower on colman gas furnace will not come on. (have no gas yet)


I'm not a furnace technician. But I have worked on several Coleman trailer furnaces. So keep in mind that my terminology might not be exactly correct. But I think I can help you.

I don't know what model you are running, but most of them run pretty much the same. You have a four basic components to check. Thermostat; Ignition Control Module; Pressure Switch; and which ever of the following that you have (Glow plug, Electronic ignition, Pilot Light).

I'm assuming that you are referring to the blower as the "Rat wheel blower" (round wheel looking thing with fins on it). If my assumption is correct and if the power from the breaker box to the furnace junction box (Probably with a on and off switch on top or side), than when you give it power (from breaker box and turn thermostat up) the fan (not blower) comes on. If it doesn't there is a probably a problem with your Thermostat or Ignition Module. If it does come on and your glow plug or you igniter tries to work. Than yes, you are correct, you have to have gas pressure to let the pressure switch know that there is adequate gas supply pressure (gas- 5 to 7 W.C, propane 11 to 13 W.C). The reason for this is if the Pressure Switch doesn't feel the correct pressure. It thinks you have a leak and won't release gas for ignition. After you turn the gas on. If the furnace doesn't ignite. Make sure the Thermostat is definitely wired properly. Now we are down to one of three problems. If the Glow Plug, Electronic Ignition, or pilot light are working properly. Than we are down one of two problems. The Ignition Module or Pressure Switch. Check pressure on the Pressure Switch. If yuou don't smell gas it is probably OK. But it is best if you use a manometer. I have rarely found Pressure Switches bad. Normally if I get to that step. It is the Ignition Module. The Ignition Module kind of like the brain of the furnace. It is located behind one of your front panels. It will have approximately 10 wires going to it. Some will be going to the Thermostat, some to the Glow plug (Igniter), some to the Pressure Switch, and some going to the blower.

I have probably said more than you need to know. If I did I apologize. But to wrap it up. You were probably correct. You definitely need gas for the blower to kick on. The furnace has to light and heat up before the blower will Start. Not to keep rattling, but to check to see if the blower motor will run. Is to switch the Thermostat from "auto" to "run".

Good Luck
