GENERAL TROUBLE SHOOTING GUIDE (con't)
TROUBLE
Contactor chatters.
15 lbs. safety valve blows off
prematurely.
Boiler build up to pressure, shuts
down and fails to come on.
Airvent leaking.
Cold water condenser does not
function.
Product in cooker does not cook
properly on first cycle, but cooks
alright after first cycle is exhausted.
Contactor chatters.
Welding or freezing.
POSSIBLE CAUSE
1. Incorrect supply voltage.
2. Dirty or worn contactor points.
3. Weak coil.
1. Pressure set too high.
2. Pressure gauge reads incorrectly.
3. Mineral build-up or dirt on seat of
valve.
4. Weak spring valve.
1. High limit switch set too low or
operating pressure control switch
set too high.
1. Not closing.
1. Main water line shut off.
2. Thermostat defective.
3. Tighten coil nut.
4. Check solenoid coil for continuity, if
open replace.
1. Airvent is closing.
1. Low voltage.
2. Defective or incorrect coil.
1. Abnormal inrush of current.
2. Low voltage preventing magnet
from sealing.
3. Short circuit.
REMEDY
1. Check to see that it matches it with
coil contactors.
2. Clean or replace contactor.
3. Replace with correct voltage coil.
1. Readjust.
2. Replace.
3. Clean.
4. Replace valve.
1. Follow instructions for readjusting,
see (page 7), or replace if defective.
1. Replace.
1. Turn on.
2. Replace if defective.
3. Tighten coil nut.
4. Check coil for continuity, if open
replace.
1. Replace.
1. Check voltage condition. Check
momentary voltage dip during
starting. Low voltage prevents
magnet sealing. Check coil voltage
rating.
2. Replace coil, rating of coil must
match the line voltage.
1. Check for grounds or shorts in
system.
2. Correct voltage condition.
3. Remove short fault and check to be
sure fuse or breaker size is correct.
