Re: wall gas furnace

Look inside the control panel of the heater. look for a 120 volt to 24 volt transformer.  There may be a fuse on the transformer secondary.  The thermostat switches a hot 24 volt wire so you won't find a common at the thermostat.

Pretty much the only thing that will do that is the thermocouple not generating enough voltage for the valve to say it's OK.
Usually you need to hold the button for pilot lighting for 60 seconds. You can use a meter to check that it's generating enough power. The thermocouple has to be in the pilot flame properly.

Heater won't come on

The first thing to do is verify that you have power to your heater.If you have a volt meter you can remove cover from electric box inside furnace and set meter to a.c. volts and check across black and white wires. You can also turn your thermostat to fan on setting and fan should run if not you may not have power to heater or bad t-stat.
After you're sure you have power to heater turn thermostat to auto and heat. Turn temp setting up high enough to call for heat. See if your induced draft motor comes on. If it does not then check electrical connections or replace draft motor.If you have power to heater and t-stat is good if draft motor does not run then nothing else will work.
You can by pass t-stat to see if it's the problem by removing cover and and taking base off the wall to get to stat wires. Locate wires that are hooked to terminals marked R or Rh and W. Remove these wires and touch them together. If t-stat is bad this should make heater come on and run. If this works then you need to replace stat.
If this does not help you please let me know and tell me what you have found and I will do my best to assist you. Thank you

TH8320U1008 Honeywell touch screen thermostat temp will adjust with down arrow but not with the up arrow


Whoa, that stinks..... I think that is the first problem I have seen with those t-stats... they are very dependable....

I would take out the batteries and let it die for about a day....I think it takes that long for the capacitors to fully discharge... Don't know what you will do for heat while your doing that, unless you know how to jumper the furnace... R-W on the circuit board will get you heat....
Then reinstall the batteries and the t-stat and see if it comes back....

Oh and make sure you also leave it off of the wall so it don't get power from the furnace either... you want it to completely die... then you will have to reprogram it... so I hope you still have the manual...

Connect my 24 milivolt gas (between the studs) wall furnace ( in my hall) to my thermostat that operates my electric heat central unit. problem: to sync both units to give home more balance ( hall is...

the first problem is you need a milli-volt t-stat and your central has a 24volt t-stat if you connect the 2 it will fry the controlls in the wall heater the second problem is t-stat location if the wall heater is near the central heats t-stat it will shut off the central to soon . maybe relocate wall unit to coldest room ?

I have a Coleman Evcon gas (propane) furnace. When the t-stat is switched to heat the furnace heats up but the blower will never turn on. The unit then shuts down and tries to cycle again. I have replaced...

If the unit fires but the main blower fan doesn't come on the the unit is shutting off on a temp high limit switch and it sounds like the problem is the main blower fan motor or control

My furnace is about 14 years old it's a modle GMP075-3 and it will come on even if the thermostat is off. I even tryed disconnecting the thermostat and it still came on.

Hi, What is happening is the control wiring from this thermostat is touching on the heat side from somewhere in the wall back to the furnace, so it calls for heat. It gets its power from the transformer on the furnace. Try disconnecting it at the furnace and it will shut down. If this is heat only, should have only 2 conductors and they would have to be touching somewhere. Look carefully at the wiring behind the stat and around the furnace for it may have melted together or bare spots where it is touching. This is the only thing that would make it come on with out the stat. Please let me know what you find. You can also ohm the red and white out to see if there is continuity, and if so, they are touching and you will either need to find it or run a new set of stat wires to solve this. Get back to me. Good Luck,

Pilot lit, flue open, wall switch on. big fire won't come on?

Assuming this is a wall furnace, take a AA battery and attach one wire to each end, tape or use holder from toy at 99 cent store!!
look at the pilot assembly, 2 wires(may look like one) go to the gas valve. at the gas valve it will be 2 wires attached to the gas valve.

this powers the whole thing! simply atach the 2 wires from batt, to where the pilotwires go (not the thermostat wires, the pilot generator)
tryt now ! does it work? if not , bad valve or try connecting the two stat wies together at the furnace instead of stat doing it to test if stats bad or wires bad. dot keep using it with battery if your sleeping or leaving etc, as ,if the pilot blows out, the gas can flow as if a plt flame existed!!!
flooding gas out into a flameless environment.

Goodman furnace

double check your wiring. R terminal on the furnace will provide 24 volts to the t-stat. W terminal in the t-stat will send 24 volts back to the furnace W terminal to turn on the heat. G terminal in the t-stat will send power to the G terminal in the furnace when the t-stat is switched to fan on. Y terminal in the t-stat will send power to the Y terminal in the furnace which in turn will send 24 volts to the A/C outside. The C terminal in the furnace should be connected to the c terminal in the A/C outside as well as to the T-stat. Check the fuse again

Furance will not stay running


Check your manual for your t-stat to be sure that it is set to your type of heating system, this is usually the cause. In the manual for the t-stat, it has settings for your type of system. You state furnace, that means it blows warm air, a boiler circulates hot water. This is most likely the cause of your heating system not operating.

I am assuming that this is a gas system. It sounds as if you are getting ignition, which is good, but not any fuel. I ask that if you are not familiar with gas systems to call a professional, but you can hear if the gas valve opens by starting it up and if you hear a series of clicks and the sound of air coming through, then the valve is opening. It can be a number of things and you will need a multimeter to check the operation of all the connections and relays.

Hope this helps.
