You should have a thermocouple in the unit for the pilot light. See if the pilot is lit, if not you may need to replace the thermocouple, if it is then check the voltage to the gas valve, if you have volts 24 volts there, your gas valve is bad. If you do not have 24 volts to the gas valve, then it's probably a limit switch.

Ruud gas furnace burners won't ignite


Remove the stat cover and jump out the red and white wires. If the furnace still doesn't come on, it is your t-stat. Replace it.

Furnace burners won't ignite


Assuming this is a gas furnace, when the thermostat calls for heat the pilot heats an igniter to produce voltage that opens the burner gas valve. In your furnace, the igniter may have failed and the burner can't fire up

I've got a 23 yr old 30DV3 whose pilot light works, and the thermostat & heating element seem to work, but not well. With the thermostat set at full hot, it just barely throws out any heat at all. ...


As I'm sure you already know, Empire Comforts Systems, no longer makes that model heater and hasn't for some years, now. I mentioned that, because if your unit needs parts, they may be almost impossible to get. In any event, there are a several things that may be causing the problem.

  • Low Gas Pressure - Burner is not receiving enough gas. Check for obstructions and have gas pressure at the unit checked.
  • Clogged burner or air intake (venturi valve) is partially clogged. Clean burner ports and venturi valve.
  • Gas line Shut Off Valve at heater not fully open. Check Gas line Shut Off Valve.
At 23 years old, you've gotten your money's worth out of this unit and it may be time to replace it. Empire makes several Direct Vent Wall Furnaces that are rated as High Efficiency Furnaces. In the long run, the money saved in fuel cost, would be worth installing a new one.

Hope this helps you solve the problem.

Furnace has new board, and ignitor but still not producing heat what could be the problem


If the furnace is less than 10 years old you will have a diagnostic light that will blink a code. You will need to find the viewing port to see how many times the light blinks and then look at the wiring diagram on the reverse of the front panel for a starting point. If you first remove the panel, it will erase the code so you must look thru the viewing port. Once you get the code read the following:

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.

Coleman Propane Furnace Good pilot light but feed/ignite main burner


If you have a volt ohm meter take the two leads off the gas valve and ohm out the connection should have resistance for the coil. You said you have 12 volts from the thermostat white and red in the heating mode you should have minimum 26 volts. If you want to check the transformer should have 28 volts. Almost sounding like the transformer is getting weak. You can get parts for a 20 year old unit at any HVAC parts house. Try Washer Specialties here in Wichita Kansas they are on the web. Lowes even carries Transformers. Has to be rated 120 volt primary side secondary side 24 volts and 40 VAC.

Amana Air Command 80, 20 years old. Electronic ignition. Furnace does not start. Good power to furnace. Themostat properly set. Where do I start looking? Bob


Hello Bob,
Welcome to fixya,

You said, Amana Air Command 80, 20 years old.
Electronic ignition.
Furnace does not start.
Good power to furnace.
Thermostat properly set.
Where do I start looking?

Sounds like you possibly have one or more bad jets if the unit is a gas furnace!
Let me know how it goes.
Huuum

WOW, listen to this story!
I understand you are looking for the solution to fix your furnace your self.
But I want to tell you my story about my smart wife and our furnace.
When we moved into this house the furnace was 20 years old and she suggested that we put a new one that it will save us money.
I laughed at her and replied if it's not broken why fix it!
Six years later it finally broke down and I replaced the whole furnace and central air unit with a new one.
Our utility bill went down $100 dollars a month!
That's $7200. that I lost over 6 years due to not respecting my wife's power of reasoning!
If you can afford it or can get financing replace any unit 20 years old and it will pay for it self.
Can you imaging $1200. a year for 20 years is $24,000 dollars I'm saving with a new and efficient unit.
Do the math!!!!!!!!!

Thank You,
Huuum, Hope I gave you some good fatherly advice.

Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.

Check the heat anticipator setting on the thermostat if its a mercury type thermostat. It may not match the proper amp draw. Take the cover off and it is a little metal lever. Try different adjustments to see which are better. If its a digital thermostat it may have an internal setting. There are several other possible reasons this could happen but that would be the most likely. for more infor on self diagnosis or the like check out my fave website Ra-Jac Air Conditioners and Heaters TX for repair information.

PS: If its a new installation it should have a one year warantee so call back the person who put it in. If you did it yourself be extremely careful gas furnaces can be dangerous. You might want a service person to check the job out for safety hazards. Good Luck with it.
