The upper thermostat keeps tripping. Any ideas why??? 1 Dec 2003 at 10:40 pm #295454 DUNBARParticipant You might have either a wire that is not properly connected or the thermostat is not the exact match to the heater. Make sure that the thermostats are identical for its use. 2 Dec 2003 at 8:16 am #295455 SelgasParticipant Why did you change only the upper thermostat – there is some reason for this action? Have you tested the lower thermostat at all?
