Reclaimer 90, short cycling?
I have a Reclaimer 90, 90% efficient furnace, that is experiencing a few problems. This is a new to me install also. when commanded to come on by the thermostat, the exhaust blower comes on for at least 2-3 minutes before the burners come on. Once the burners come on, the temp limit switch located on the unit rises and then shuts the burner off due to the temp getting too high. As soon as the temp drops, the burners kick back on. The blower stays on the whole time and the air never blows cold, but the temp within the house doesn't rise above 68 degrees due to the constant cycling on and off. Please let me know if you have any ideas. Thanks
