Fridge does not use a thermocouple
It uses the Spark Electrode for ignition AND Flame 'Proving'
If milivolt signal generated when flame lights off doesn't get back to circuit board ,...board shuts down gas valve so raw fuel isn't building up
Spark electrode needs:
To be CLEAN---use emery cloth to clean
To be 'engulfed' in flame----tip should be centered over burner slots and turn red
To be properly gaped---1/8" - 3/16"
To be grounded.....mounting screw provides ground contact---clean/tight
To be insulated....ceramic can not be cracked. (watch at night for tracking)
To have good clean tight connection
