Re: pitco fryer pilot out
If you changed the thermopile and still have the same problem make sure that the sensing bulb is directly over the flame. If it is and the thermopile is installed correctly the next thing would be the gas valve.

Hi there. Try cleaning the thermopile, it must be free of soot or any form of dirt. Ensure that the gas pressure is sufficient, all wiring connections are tight and the hi limit is good. If all of these are okay and the pilot still wont stay lit, try replacing the thermopile.

Check the gas pressure, it must meet the standard gas pressure written on the nameplate. Check also the quality of pilot flame, poor pilot flame quality will not properly heat up the thermopile which in turn will result in poor fryer operation.
Check if the the gas pressure is sufficient (as stated on unit's nameplate). Check if the hi limit device is good. Check also if the thermopile (cylindrical metal with two wires standing behind the pilot hood) is receiving enough heat from the pilot flame. The voltage generated by thermopile should be 500millivolts in order to open pilot and main valve. If there is 500millivolt on gas valve thermopile and the pilot flame does not stay lit, you have to replace the gas valve. If the thermopile is glowing red and the voltage generated does not reach 500 millivots, you have to replace the thermopile.
You have to check the following: 1. Does the pilot flame has the ability to heat up the thermopile? Themopile must be properly heated in order to generate voltage to open the pilot valve as well as main valve. 2. When the thermolpile is heated, does it generates 500 millivolts? If not, your thermopile needs replacement. If it does and still the pilot flame wont stay lit, your gas valve needs replacement. 3. Does the hi limit device has continuity on its terminals? If there is no continuity on hi limit terminals, you have to replace it. One of the thermopile wire passes on this hi limit terminal to cut the voltage supply on pilot valve in case the oil temperature reaches 450F. 4. Check and tighten all wiring connections, millivolts generated by thermopile will not pass on loosely terminated wiring.
Check the thermopile, it must be free of dirt or soot so that it can absorb enough heat from pilot flame and in turn can generate the right amount of voltage to energize pilot and burner coils. Check also the gas pressure, it should be of standard as required on the unit's nameplate.
