Arrived at location on 2/28/22 - Vulcan fryer is not working, pilot goes out when thermostat Is turned on. Attempt to light pilot, unable to light pilot at all, no millivolts at gas valve. Hi limit is closed. Disconnect thermopile and have reading at leads when disconnected from valve. Reconnect and millivolts go away. Shorted thermopile. Replace thermopile. Test, now have proper millivolts at gas valve. Burners now light properly. Allow to heat up. Unit is functional. Ok for use,
