Question about Patton MH761 Utility Heater
The red caution light comes on after approx 45 seconds....heater will shut down, then come back on after approx 1 minute....it just started doing this for no apparent reason...heater is approx 3 yr.s old but has very little running time (use) on it.
The red light is in conjunction with a safety. This is there in case something goes wrong, the heater doesn't overheat and possibly catch fire. If its not getting too hot, and its sounds like its not. The safety needs to be replaced. It will be a little disc shaped thing with 2 wires connected to it. If this heater also has a tip over safety, there also may be some type of mercury switch too. If you are so inclined, when you find the safety disc it should have some numbers on it. This indicates the temperature it is made to turn off at. After removing it, connect the 2 wires together and turn the unit on with a thermometer in the spot where the disc was. If the temp. doesn't go higher than the #'s on the disc after 45 seconds like you said, then you know positively that is the problem. If it gets hotter very fast, then the elements need to be looked at for defects. If there are no numbers on the disc or you cant find a replacement, then it may just be easier to buy a new heater.
