I have a Comfortmaker RPJ II that recently stopped working. The blower starts up, but the pilot is not lit and does not seem to ignite so the unit simply blows cold air. This happened one time before and it required a new thermostat. I replaced it again simply to prevent the same occurrence. No change in results.
I put a multimeter on the ignitor port on the gas valve. One was at 30v, the other did not register anything. Is this correct? If not, what should I check further?
