Hi,

The relay on the circuit board for the inducer is stuck closed....
The reason you have to turn down the t-stat or recycle the power is that for the system to refire the pressure switch must open and then close again, which it does in either of those cases....
To fix the problem you will need to repplace the circuit board....

Check with your dealer for a new board or you can buy it on the internet...

My good man furnace model gmh80903bnca will not get to temp fan shuts off and burners keep burning then kicks off on high limit then starts process over but never gets to temp set at 655


If you have a switch that can manually turn on the fan, try it to verify the fan works. This is what I think is happening. The normal operation should be thermostat calls for heat, inducer fan comes on, pressure switch closes, igniter glows, main burner ignites and then in 30 or so seconds the fan comes on and stays on until the thermostat is satisfied. Once the thermostat is satisfied the burner shuts off and the fan runs for approx 120 seconds then shuts off. I think the control board that automatically turns your fan on is faulty. On most modern furnaces if the auto fan control fails and the furnace gets to hot and limits, when the limit opens and shuts off the burner it also energizes the fan motor to cool the heat exchanger.

My Honeywell smartvalve stop opening the gas valve, inducer motor started, glow and pilot happen, just no fire...I replaced said smartvalve and upon installation, the inducer motor wouldnt run, no glow or...


Smartvalves are tricky and a certain sequence must happen. Without going into this in depth, try this:
Install new smartvalve
Set thermostat to the off position
Kill the power to the unit
Restore power to the unit
Turn the heat on with the thermostat
In this order!

Have an older Coleman mobile home furnace (Mdl 8665D766). Both blower fan and booster motor work fine; however, during heating, booster motor will keep constantly running after system cycles through


The booster motor? Do you mean the inducer motor that helps push the exhaust? If the inducer motor won't shut off when the thermostat is satisfied and everything else does shut off, it sounds like the contacts on the relay that powers the inducer are at fault

Draft Inducer problem


On the call for heat from the thermostat the inducer should come on first, a pressure switch proves that the inducer is moving enough air up the stack, closes and energizes the ignition and burners come on. 30 to 60 seconds later the blower comes on. Everything should stay on as long as the thermostat is still calling for heat. When the thermostat is satisfied the burner and inducer shut off and the fan will run to remove the heat from the heat exchanger and then shut off. Cycle complete. Some inducers have a post purge so when the thermostat is satisfied the burner shuts off, the inducer runs for 30 seconds or so and then shuts off. I am thinking that your furnace may be running on the limit switch and when the burner is off but the inducer stays on, maybe the limit is shutting of the inducer. Check your air filter and make sure all your heat registers are open and that the return air grill is not blocked.

Pilot lights up but would not fire up into heating, I have brivis buffalo 85


This is the proper cycle of a furnace and what should happen.

Inducer motor kicks on, it runs for a little bit, about 3-5 seconds, then you should see a bright yellow glow, this is the igniter, shortly after, you should hear a click and the gas should start to flow, almost immediately it turns to a blue flame. Then your igniter should turn off and the blower motor start up.

If the pilot turns on and the gas ignites, then shortly after the unit shuts off, chances are this is your blower motor. It is not starting up, then the heat limit is reached in your unit and the safety shuts it off.

I have a Arcoaire Gas Furnace (Model# GNJ100N12A1), that will not fire up. It has a White Rogers Digital Stat. First the Stat seems to be faulty, since it reads 70plus in a house that has a temp of 30...


Sounds like a faulty board. shut the power to the furnace off for a minute then turn it back on. Make a call for heat at the thermostat. The inducer should start and close contacts on a pressure switch . Once pressure switch closes the hot surface ignitor should glow red. Then the gas valve will open when the gas valve opens you should get fire till the stat is satisfied. If your concerned it is the jump out r to w on the board this will eliminate the stat. If you to reset the rollout switchs 3 timesyou're getting flame rollout and you either have a cracked heat exchanger or blockage in the exhaust piping or a bad inducer motor. Keep me posted with what you find!

Induction fan motor cycles on and off , with no call for heat


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution: You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Gas Furnace will not start when outside temperature rises to 50F


There is a pressure switch near your draft inducer motor that needs to close when draft inducer motor is running. Verify that the switch is closing. If it is not closing, you might have a problem with either the switch itself, or there could be some sort of blockage in your flue. I would start with the switch first. This switch has to "prove" before it will allow anything else to happen. The loud click could be from your switch or your gas valve. If the switch is closing and nothing else is happening, it could be a problem with your gas valve or HSI.
