Model 3E225 fan comes on but main gas will not ignite

    I had this same problem, I found that there was a bad connection on one wire at the back of the main valve.
    Try lighting the pilot light, turn the thermostat so the fan comes on, then move or jump the wires to the valve and see if the main burners come on.

My furnace works on ac and blows on ac but on heat it does not blow but i hear a humming sound coming from the furnace


Most furnace operating on Oil or gas will heat the combustion chamber before starting fan to prevent cold air draft at start-up, can last a minute or two. Eiter the main flame does not come on or the chamber thermostat have fail. Try to modify fan option on room thermostat from auto to on. Cold air coming out: burner problem or no more oil or gas, warm air: burning chamber thermostat problem, leave room thermostat fan option to on until repair.

When the heat cycle calls for gas there is no ignition is my gas valve bad?


I don't know what kind of furnace you have. But most furnaces have some sort of pilot first than after it is proven than the main gas will come on. Either a standing Pilot with a thermocouple. A hot surface ignition or Spark ignition with a flame sensor. Or a direct fire system where hot surface or spark ignitor start first than all the burners send a 1 sec blast of gas which is proven by the flame sensor if it proves the gas valve stays on.....
In what you have said you have 24 volts to the gas valve and it has not lite. then does the gas valve have a pilot tube???Does it have a thermocouple?? Do you smell gas?? If you don't smell gas then the main part of the valve has not opened. The Pilot valve has to open first and prove before the main gas will come on. I hope this helps. If you still need help repost with the name and model # of the furnace.

Goodman a/c @ heating unit. Model #gmh80703anca when I turn the unit on it keeps blowing the fuse on the circuit panel. What could be causing this?


Several questions:
1. What fuse? 110V at the furnace? Breaker at the house? Fuse on the controller board?
2. Does the ignitor work? Do you get gas ignition?
3. Does the exhaust fan come on?
4. Does the main blower come on?

Bradford White gas power vent water heater; just replaced power vent motor and fan assembly because a bearing went out. Now the new fan motor runs constantly without igniting. Is there a switch that...


Some how you have disconnected the sensor that tells the main burner that the fan is on. Its trying to light but cant. On some models there is a air pressure switch that reads the pressure inside the vent pipe itself. It will have a small hose on it and if that has cracked or was not replaced it wont light. This is how its supposed to work--- vent fan comes on,sensor confirms fan is on,hot surface ignighter starts to glow red,and main burner is opened,another sensor confirms that main burner is lit,then hot surface ignighter turns off. Hope this helps.

Pilot lights but no main burner


Is there a way to check for gas pressure even if just a slight loosened connection to hear it then quickly re-tightened. Otherwise the main valve is not working as it should and will need to be serviced or replaced. Thats all i got.

Turn main furnace switch on, combustion air fan comes on and main circulation fan comes on. About 40 seconds later the igniter lites, two burners closest to the igniter fire up and immediatly snuff out....


Hello, if all the burners are not firing up then they must be cleaned out, usually dirt gets in the crossover parts of the burner and the gas cant flow to all the burners and therefore the flame sensor will turn off the furnace for safety. Clean the burners out this should fix the problem.

Check gas pressure, inspect manifold & make sure there is not a blockage.Make sure gas is present and main gas shut off valve to furnace is on also check the knob on the 24 volt gas valve and see if it is in the on position , check the MV terminal on the gas valve to 24 volt common with a volt tester to see if you have 24 volts present, if you do have 24 volts at gas valve, replace valve. if you do not have 24 volts at gas valve check high limit control & roll out limits for a open circuit, Good luck.

I have a Dayton gas heater Model 3E225


Does the main blower fan kick on? Also, if the heater is vented outside via a flue pipe, there may be a small (about 3 or 4 inches in diameter) vent fan that kicks on to ensure the exhaust fumes are evacuated through the flue pipe. If there's a problem with that fan, the burner won't light either.
