My Pitco fryer is shooting large flames out of the door. . . . HELP!

Question moved from Misc

HEAT FAILURE - This means the heating system has failed to respond, which can occur because a high temperature limit switch has been tripped and needs resetting. On gas deep fryers, "HEAT FAILURE" may display if the pilot fails to light or if the pilot flame is too weak as detected by the ignition module.

You have a clogged burner. It probably has carbon build up and that's pushing the gas outside the tube to burn. If you can remove the burner you can flush it out with water. Beware, it's messy. You will get carbon black all over everything.

Hi Dan.
Check if the fire tubes are clean, exhust system must be operating well during fryer operation. There should be no fresh air directed at the flue stack of the fryer, only exhaust.
Regards.

Hi there.
The soot or carbon have probably build up inside the fire tubes, better check and have an authorized service technician clean them.
Make sure that the fryer is receiving the rated gas pressure and correct gas type as stated on the nameplate, this way, carbon or soot formation on fire tubes can be prevented
Regards.

Hi there.
Check the gas pressure and gas type being fed to the unit if they are correct, low gas pressure will result in poor flame quality which will in turn produce carbon or soot inside the fire tubes.
Check also the condition of the fire tubes inside, they should be free of carbon or soot deposit.
Regards.

Check if your pilot flame sufficiently heats thermopile during operation and make sure also that it is free of soot or any form of dirt, thermopile generates small amount of electricity to energize pilot and main valve of the gas valve for pilot and main burner operation. This electricity passes through hi limit mechanical contacts. Hi limit on fryers act as safety device which will shut down pilot and burner flame when oil temperature reaches 450F.
If your fryer is set at 350F and over shoots up to 450F (which will trip hi limit and shut down pilot and burner flame), the thermostat is not good, but, if hi limit trips on temperature much lower than 450F, hi limit is bad.

Low gas pressure will produce low flame quality (yellow flame).
Check and remove any dirt or soot on burner holes, and orifice
Burner flame not going inside the fire tube could be due to soot or carbon build up inside the fire tube blocking the flame path, check the inside of the fire tube, if considerable amount of soot is seen, better have them removed.
Yellow flame will cause a lot of problem on fryers if not corrected as soon as possible.
If you have doubt on your gas regulator, better have a qualified service technician to check it.

check burners and chambers for soot build up. Check gas regulator valve

It sounds like you are not recieving a heat feedback signal. It may be as simple as cleaning your flame sensor, using a emery cloth/ scotchbright. Be sure that all gas is turned to the on positions. Also that any safty high limits are closed / reset.


Scoota

my friend it looks as if you have a leaking frypot. Do not use this fryer untill the frypot is replaced it is dangerous to use in this condition.
