Question about Dayton (3E386) Heater
I have an old 75 K BTU Dayton shop heater in a large (approx 24' x 48') garage. For the last two years it has started to produce heat only in short cycles. The burner will come on for a time, maybe up to two minutes and go off as the fan comes on. The burner will then immediately come back on for a short time and again shut off as the fan cycles on. It will repeat these short cycles until the thermostat senses the set temperature. The heater did not work this way before. It used to run continuously until the set temperature was reached. What could be causing this change in operation?
The sensor for the thermostat is probably going bad or has bad connections. It is (or thinks it is) heating up fast and therefore shuts of the heater.
