Hi, I'm wondering about the following. I have a hood fan at a fast food restaurant and for a while now there's been a situation where some days I go to turn it on in the morning and it goes out a few times. Some days it happens, while some days I flip the switch on and it runs normally. When it goes out I have to go to the circuit breaker box to trouble shoot it in order to get it going again. Is an issue like this a fire hazard or is the trouble shooting saving it from a fire while still indicating there's something going on?
