GENERAL TROUBLESHOOTING
TROUBLE POSSIBLE CAUSE REMEDY
Air vent leaking Not closing Replace
Cold water condenser does not
function
Main water line shut off Turn on
Thermostat defective Replace if defective
Tighten coil nut Tighten coil nut
Check solenoid coil for continuity, if open re-
place
Check coil for continuity, if open replace
Product in cooker does not cook
properly on first cycle, but cooks
alright after first cycle is exhaust-
ed
Air vent is closing Replace
Contactor chatters Low voltage Check voltage condition. Check momentary
voltage dip during starting. Low voltage pre-
vents magnet sealing. Check coil voltage rating
Defective or incorrect coil Replace coil, rating of coil must match the line
voltage
Welding or freezing Abnormal spike in current Check for grounds or shorts in system
Low voltage preventing magnet from sealing Correct voltage condition
Short circuit Remove short fault and check to be sure fuse or
breaker size is correct
Short contact button life and / or
overheating of contacts
Filling or dressing Do not file silver tips. Rough spots or discolor-
ation will not harm tips or impair their efficiency
Interrupting excessively high current Check for grounds, shorts or excessive current
Discolored contacts caused by insufficient con-
tact pressure, loose connection, etc.
Check contact carrier for deformation or dam-
age, clean and tighten connections
Dirt or foreign matter on contact surface Clean with Acetone
Short circuit Remove fault and check to be sure fuse or
breaker size is correct
Open circuit Mechanical damage Handle and store carefully. Do not handle coils
by the leads
Burnt-out coil due to overvoltage or defect Replace coil
Overheated Coil Over-voltage or high ambient temperature Check application and circuit
Wrong coil Check rating (voltage and frequency) if incor-
rect, replace with proper coil
Shorted turns caused Replace coil
Under voltage, failure of magnet to seal in Correct system voltage. Install new coil
