Hello i have an electric Pitco Frialator and when I turn it on the light comes on but it doesn't click and doesn't heat up. What could be causing this?

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.

Replace the thermocouple.

Thermostat calling for heat.

The output flu should not impact this. What is impacting this is airflow from another source coming into the building. For example if a window is open on the windward side then airflow will rush in and exit through the flu. This could cause the problem. The other thing you should check is the gas pressure on the supply line. An indication that the gas pressure is too high is a gap between the end of the pilot jet and the base of the flame. Another concern is a venturi effect if the area between the hood and the fryer is too small.

Hi there!

Try first to clean the thermopile. If it has accumulated soot/ carbon, it will not sense enough heat from the pilot flame to generate small amount of electricity to energize the pilot valve and main valve of gas valve.

If your fryer has computer controller (the one with 8 product buttons and left, right arrow), check the display when you turn off the computer board, it should display "gas 2". If not, you have to change the gas configuration by accessing the programming mode.

You need to identify where the leak is coming.
If the leak is on the fry tank, best way to address it is to replace the oil tank.
Check the serial number of the unit with leak on fry tank, verify if it is still under warranty at PITCO web on http://www.middleby.com.

Try to spray wd40 on knob.
If spraying wd40 doesn't work, you have to replace the gas valve.

This is caused by a failing pilot safty bypass inside the gas valve itself. You will need to replace the gas valve.
