Thanks Gary. I looked for a fuse or breaker in the heater and nothing I could see. I looked the heater up on the internet and nothing I could find on any type of fuse. I have back up heat in the garage so will take the heater down and I guess tear it apart and check the heating elements. I checked breaker in the shop fuse box and checked the wires also and it all looks good. Thermostat on the heater is working and the fan kicks in so thinking the heating element is shot. It's only been in the shop running for a year and a half since new and maybe it is just to small for the size of the garage and over loaded?
