Hello, my furnace has quite working so I don't have heat. It's 10years old Rheem Modle# RGPJ-07EAMGR. A friend came out and thought the problem may be the thermostat or the igniter, so far I have replaced the thermostat and the fan motor runs without cycling, even when I turn the system off or switch between heat and cool, also there's still no heat. I live in Houston Texas, and haven't been able to find a replacement igniter either.

Any ideas?

Google. Rheem Ignitor. Unless you have something very different, there are lots of sources. Any HVAC parts distributor should have them. Johnson Controls, Ferguson, Eds parts. You should really do some testing before just replacing parts. Could be lots of things other than a thermostat or an ignitor. Does the inducer fan come on?
