I have a Purex Triton Minimax plus 400 that shuts off after the heater has been running for ~ 1 minute. What things should I look at to trouble shoot the problem?
It seems that the problem is related to heat. I pulled off the main header and check the baffles for blockage and all seems fine. Could this be a problem with a thermostat which is shutting down the unit?
Also noticed the pressure sensor is looking worn. But if this was bad I'm thinking the furnace would not fire at all. Is this correct?
Anybody have advice?
