c.Make sure the electrical connections are clean and tight. Replace damaged wire with
d.Check to see if ceramic insulator is cracked. A cracked insulator can cause a short to ground. Replace the igniter- sensor if necessary.
e.At the gas control, disconnect the main valve wire from the TH or MV terminal.
f.Connect the fryer to the power source and move the on/off switch to the ON position.
g.Turn on the power and set thermostat above 200°F/93°C to call for heat. The pilot should light, but the main burner will remain off because the main valve actuator is disconnected.
h.Check the pilot flame. Make sure it is blue, steady, and envelops
i.If necessary, adjust the pilot flame by turning the pilot adjustment screw on the gas control clockwise to decrease or counterclockwise to increase the pilot flame. Following adjustment, always replace the pilot adjustment cover screw and tighten it firmly to assure proper gas control operation.
j.Set the thermostat below 200°F/93°C to end the call for heat.
4.Recheck the ignition sequence as follows:
a.Reconnect the main valve wire.
b.Set the thermostat above 200°F/93°C to call for heat.
c.Watch the ignition sequence at the burner.
If the spark still does not stop after the pilot lights, replace the ignition module.
If the main burner does not light, check for 24V AC across
