Question about Heating & Cooling

1 Answer

I turn on the power switch and the blower turns on and stays on. I can get the pilot light to stay on but the burners will not light even after I turn the RED gas valve to ON. There is no thermostat installed but I shorted the red and yellow wires together to simulate ON and I hear some clicking but still the burner does not light. I know there is propane because of the pilot lite and the stove,hot water heater are working. What can I do?

Hello Skyhalliday,

I understand that you are having a problem with you central heat/air. You do not have a thermostat installed and have the red and yellow crossed in order to make the unit run.

The wires you have crossed are not to the heat if they are to the common color code. Here is the color code for HVAC units:
Thermostat / Wire / what is controlled
W / White / Heat gas valve or heat elements
Rc(Rh) / Red / 24 volts transformer
G / Green / Fan
Y / Yellow / Air Conditioner Outside unit
C / Blue or Black / Common (energizes thermostats that do not have batteries)

You may not have the proper wires shorted in order to have the burners engage.

Thank you for choosing FixYa.com

When I try to use my Thermolaire model SU402E, the pilot lights( and stays lit), but the main burner will NOT ignite.. any suggestions as to what could cause this if the pilot stays lit?


Bad igniter? When you 1st try it the gas valve will give enough gas that you would get the burner lit if the igniter was glowing red. If you're desperate you can light the igniter area w/ an aim n flame, but you definitely want to do that w/ caution and crank up your t-stat so the furnace stays on awhile Cuz you'll have to do it again for heat or buy an igniter($40 or so)

Janitrol GUPS075-3 Furnace burners will not stay lit


The first thing I would do is make sure the flame sensor is clean, this is a metal rod immersed in the burner flame on the opposite side of the igniter. If too much oxidation builds up on it, it will not allow the burner to stay lit. To clean, just turn off furnace and remove flame sensor and clean with steel wool and then reinstall. If this does not solve the problem there may be a problem with the gas valve.

Pilot light stays lit but blower motor will not kick on


The blower won't turn on, until the burner is lit and builds up enough temperature to activate the blower.
If you haven't already, turn the control knob from Pilot to ON. that will activate the burner.

Fan turns on, pilot on left side turns on red light at bottom stays solid during entire time then pilot goes out and blower stops no heat please help


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 remaing 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).

Pilot flame will not stay on


The thermocouple is bad this keeps the gas valve open from the pilot flame telling the gas valve that the pilot is lit and it is okay to turn on the burners.

Fireplace will not stay lit and pilot light is on


This sounds like the high temperature switch has failed and is telling the unit to shut down after it gets started, the pilot has to be lit for the main gas valve to turn on when the thermostat calls for heat, The main burner comes on and stays on until the thermostat is satisfied and tells it to shut off, you dont say if there is a blower in this unit, if there is a blower after the main flame comes on the unit heats up it turns on the blower if equiped. If the blower fails to turn on the unit would be shut down on overtemp as the firebox would get to hot and be in danger of causeing a fire. if no blower there still is an overtemp switch that shuts the unit down if it gets to hot or the switch is bad, it could be a bad overtemp switch or if equiped a bad blower motor or even a plugged chimney as this would also cause a overheat ing condition. Hope This Helps Don

The yhernocoupler would snuff the pilot if bad. What ignites the overhead burners? and what regulates the overhead gas supply? Look into this. Too much gas will not light as easily as proper balance gas and air. Even more so in a tower type heater.. Turn the gas on low and the pilot should grab it. Good luck

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.
