Upon arrival Middle Fryer unit was on and not sending a hi temp alarm. 3 baskets of fries were dropped and one of hash browns. The alarm did not happen. The temperature of the oil was tested and is within range on the display. Upon inspection the one relay was removed and looks a little smoky, this could cause the coil of the heater contactor to stick. Will order 2 and have replaced. Right now unit holding temp and nothing is sticking. Will order 2 relays and return. 10/7/20 Installed 2 relays and dropped 4 baskets. Hi temp alarm did not occur. Watched unit to see if error would occur and it did not.
