Question about Heating & Cooling

Open Question

I have a Goodman GMH80904BN heater that only stays on for few seconds and then kicks off

When I turn on the thermostat it kicks the heater on for only a few minutes and then the system shuts right back off. What do I need to do to fix it?

SOURCE: heater won't stay on

This product does indeed have a problem with the safety switch, that is only supposed to kick in when the unit is turned over. I had a total of 3 units sent to me from Kaz. Each time the unit would work for a short time, then slowly begin to turn off and on. I finally decided to take the unit apart and look for any obvious problems. There is a weighted swivel that will raise a contact point to turn the unit off in an emergency. The contact points would spark off and on, depositing a black carbon on them until they would no longer allow power to pass through. I cleaned the contacts with a fine finger nail file and bent one of the contact arms inward to make better tension between the contacts. This allowed the unit to stay on for longer periods of time. But even with the thermo-stat turned all the way up, the unit does not stay on long enough to heat the room. In effect, what happens is the contacts will continue to ark, putting black deposits on the contacts until you're back to square one. Apparently the unit also has a thermo-stat related problem. I'm sending the unit back again (they only made me send the power cord last time), but will insist on a different model this time. Good Luck

SOURCE: The heater will not ignite properly and the heater will not shut off

Judging by your pics (helpful, by the way) you have a high limit wired into your thermostat wire. Try disconnecting that wire nut connection in front of your valve and hooking the thermostat straight to the top and bottom posts on the valve (eliminating the high limit). If it runs fine, either the connection was poor or your high limit wire is pinched.

pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.
• Check front cover
pressure switch
operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
signal. Sand sensor if
coated and/or oxidized.

SOURCE: oil filled heater wont stay on

I was having the same problem and did a search to find this link. This morning when I turned it on, I backed the temperature down to 66 when it first came on (defaults to 70) and it appears to be working now (it's been on for over 10 minutes)

I had the same problem with the "F" appearing and the unit turning off. I read a similar post about the hz-709, that talks of removing the "tip over sensor". To remove the sensor, "two little black boxes on one chip, that rattles like there is a ball bearing in each box."
Remove two small screws on the bottom of the heater then remove two small screws on the top of the heater "top screws are under a small cap that can be popped of with a flat head screwdriver."
Inside long panel front Unplug three wires, White Brown Blue "remember where they where plugged in, so you can plug then back in later."
Inside long panel front there is a silver panel with eight screws on it only the, only the four "corner" screws have to be removed to remove silver panel.
remove silver panel then remove remaining 4 screws, Now remove front control from long panel front, there are 6 screws only have to remove the four inner screws, Open white box, slip large chip off three prongs,
there are two small blue wires connecting to the two small black boxes from the beginning of this post, cut wire from box, twist or solder together, and tape with electrical tape.
"You have just removed/disable the tip over sensor, Unit will not turn off when knocked over!!"
Reverse steps reassemble the unit and enjoy.

Code 1 on a goodman furnace. Changed filter, reset thermostat, hit the breaker for reset and still the temp is dropping and the unit is not kicking from the thermostat. Thermostat is only a year old.


You unit is under locked out mode due fail on start up. Get sand paper clean out the flame sensor, and jump the 2 wires that go to the pressure switch as soon as the inducer came on. Doing this the flame should stay on until it meet set temp at thermostat . If it does what said your pressure switch need replacement . Good luck and keep me up to date .

I have a goodman modle gms80703ana and at first the inducer fan would kick on in it's normal cycle then the furnace would shut off do to a pressure switch. Now the inducer fan only come on perodicaly...


First unplug your furnace to reset it then plug it back in with thermostat set to heat high enough to make the heat come on. As soon as the inducer motor came on you JUMP the 2 wires that go to pressure switch. Your igniter should come on and gas valve should open for heat. If the flame stay on the blower should come on after a few minutes. If it get to this point your problem could be pressure switch itself or inducer clogged.

Goodman GMP 100-5 Rev B Serial # 9902602550 The status light stays illuminated. It isn't blinking. I believe my igniter went bad. When I turn on my heat on the system, The exhaust fan kicks on,...


Hello, the first thing is check the igniter for any crack or white spots on it, also, if you have a multimeter check the resistance of the igniter, should be between 40-90 ohms. You can purchase a igniter at any Heating and Cooling supply store.

I have 2 goodman heating systems. one for upstairs and one for downstairs. The downstairs works great. With the same temp settings on the upstairs, The blower kicks on and you hear the the flame kick on...


i have seen this just the other day customer called and there thermostat would not maintain temp... changed batteries and after five mins did it again... couple of things need to make sure you have fresh batteries if it takes them in thermostat. also try overriding program by pressing the hold button and set where you desire see if it works then... if it still fails to maintain you need to make sure the unit is not running when it is suppose to be off... if the fan is running and the thermostat is not calling for heat or cool then it is possible the flame sensor on the heater is bad or needs to be cleaned... to be honest based on what you are saying sounds like you got two different items going on....
a sure way to test if your mechanical inclined is take the t-stat apart jump the r terminal to the w terminal go to unit and unplug for 10 seconds and plug back in if everything fires up and stays going you 100% have a thermostat issue...

GMP075-3 looks good but shuts off after 10 seconds


Replace the thermostat control sounds like the control contacts are not holding since you cleaned the bulb and the igniter is working the only other issue is the thermal buld being bad, shut it off heat the bulb for three minuts then quickly turn it back on and see if it stays on longer if it does the bulb is the problem.
