The small blower comes on and the air-flow switch closes always but the gas and igniters only come on sometimes. I have checked connections and cleaned contacts, etc. I used an ohmmeter to verify that the air switch closes when the small blower comes on. The thermostat is trying to increase the heat. I do not have any service information.

Any help or information on how to get a hold of service literature would be greatly appreciated. My model is Rheem RKMA-A060JL10F

Thanks!
