I have Rheem Imperial furnace. Today itjust stopedworking. When I play with the thermostat settings, I hear the fan and air comes out of the vents except it is cold air. I checked the furnace, the ignitor does not heat up ad the burners don't light. Do you think the ignitor is the problem or isit the board? How do I find out?

It sounds like you're talking about a hot surface ignition type system. First, turn off the power to the furnace to reset it. Then, turn it on and call for heat. If the glowbar does not heat up. Take your voltmeter and see if you have 120 volts going to it. If so, the ignitor has failed. If you don't have power, check both the high and low voltage inputs to the board. The ignitors fail far more often than the boards. Thanks. John.

If your handy and careful and would like to replace that glow coil, then by all means try it. If the heater is more then 5 years old, it's likely to have a burned out coil and replacing it may solve the problem.

I would not suggest poking around with volt meter probes on the motherboard. Glow coils that fail could be caused by a defective gas valve solenoid or module or several other conditions.

Checking for voltage at the coil when it is suppose to be glowing is okay. You'll need to connect the volt meter probes first since the time duration the current is flowing there is limited.

This furnace also has several fail safe safety systems that may be causing the condition. Your best bet is to contact a local service agency.

Good Luck,

Rheem ignitors crack or break quite often.If you SEE a crack or a peice of the ignitor missing or laying at the bottom of the vestibule. You need an ignitor.
Good Luck

I called the service person. Apparently the gas line was plugged o something like that which caused it to shutdown for safety.
