Reddy Heater Wont Stay Running

Help! I have a Reddy heater that won't stay running! The Reddy heater keeps shutting off. This kerosene forced air heater is a huge asset in my shop ' when it's running. I checked for damage from mice, but don't see any.

More info needed. Could be anything from a fried board to a freyed wire. How old is it?

By "damage from mice" I assume you mean the wires?

Clean everything you can think of, from the sensor/photocell to the filter. If you haven't performed PM in a while, it's probably just dirty.
