We had a Payne (high eff.) furnace installed in Janurary of 2002. On more than one accasion the furnace would not start up when the thermostat was calling for heat. We would trip the circuit breaker for the furnace and turn it back on and the furnace would start. It runs for a while responding to the thermostat (hours, days, etc.) and then for no apparent reason does not start up again when the thermostat is calling for heat. We repeat the process of tripping the circuit breaker and it would again start up and run. We have had the service man who installed the furnace out many times and we still have the problem. It is still under warranty and we want to get it fixed once and for all. We are beginning to question our service man's diagnostic ability to fix the problem. I believe when we trip the circuit breaker we must be resetting something in the furnace electronics but our service man can't seem to find the problem. What should he be looking for? We need help!!!! The house is in northern Michigan (second home) and I can't have the furnace only working some of the time when we are not there to trip the circuit breaker.
