Report "A pitco frialator in a restaurant will operate for about 5-6 hours and then blow the pilot light and burner out. I have put a thermometer in the oil, watched it work and the oil temps wont exceed 375 degrees. the unit seems to work while i am there but it has been out for the last 2 mornings and I get called in at 5 am to re-light it so we can prepare for the morning breakfast time.Then usually about 1130am I get another call to redo this yet again as it has blown the pilot out. The thermostat when i have it up to temp clicks at 340 degrees(shut down side) and 360 degrees(light side). Where do i start looking or what do i need to replace?"
