| NO CONTROL OF PRESSURE/TEMPERATURE |
A) OVERTEMP SWITCH |
A) RECALIBRATE FROM COLD START. |
|
B) THERMISTOR ASSEMBLY |
B) RESISTANCE SHOULD BE 1 MEG W@ 77°F +20%. |
|
C) SOLID STATE CONTROLLER |
C) MEASURE VOLTAGE FROM COMMON TERMINAL OF POWER SWITCH NO.2 TO COMMON TERMINAL OF FUNCTION SWITCH. IF 120 VOLTS, BOARD IS OPEN. IF 0 VAC, BOARD IS GOOD.
|
|
D) CENTER HEATING ELEMENT |
D) POSSIBILITY OF SHORT IN HOT SIDE OF LINE. TRACE OUT HOT
SIDE OF LINE FROM POWER CORD TO SWITCHES FOR A SHORT.
CHECK CENTER ELEMENT FIRST. |
| WILL NOT BUILD UP TO STERILIZING PRESSURE/TEMPERATURE |
A) DOOR |
A) CHECK DOOR TO MAKE SURE IT IS IN THE LOCKED POSITION AND NOT LEAKING. |
|
B) DOOR GASKET |
B) REPLACE DOOR GASKET IF LEAKING

OCR Plus Door Gasket |
|
C) DOOR SWITCH (OCR+ ONLY) |
C) CHECK SWITCH POSITION AND READJUST IF NECESSARY. |
|
D) UNIT LEVEL |
D) USE LEVEL AND ADJUST FEET IF NECESSARY. |
|
E) AMOUNT OF WATER ADMITTED DURING FILL CYCLE |
E) WHEN PROPERLY FILLED, WATER SHOULD COVER FILL PLATE. |
|
F) POTENTIOMETER ON CONTROLLER |
F) TURN CLOCKWISE TO CALL FOR MORE HEAT. |
|
G) CENTER HEATING ELEMENT |
G) CHECK RESISTANCE OF ELEMENT, IT SHOULD BE:
~ 10W FOR OCM
~ 8W FOR OCR OR OCR+ |
|
H) OVERTEMP SWITCH |
H) RECALIBRATE FROM COLD START, OR REPLACE AND CALIBRATE.

I) THERMISTOR |
I) CHECK RESISTANCE. SHOULD BE 1 MEG W@ 77°F +20% |
|
J) FRONT POTENTIOMETER |
J) CHECK RESISTANCE 20K W +10%. |
|
K) SOLID STATE CONTROLLER |
K) MEASURE VOLTAGE FROM TOP TERMINAL OF NO. 1 POWER SWITCH TO COMMON TERMINAL OF FUNCTION SWITCH. (IF 120 VAC BOARD IS PROBABLY OPEN; IF 0 VAC, BOARD IS PROBABLY GOOD). THIS IS PROVIDED THERE IS CONTINUITY THROUGH FUNCTION SWITCH, OT SWITCH AND HEATING ELEMENT. |
|
L) MAIN VALVE (FILL/VENT VALVE) |
L) CHECK TEFLON SEATS FOR SCORING OR TRASH LODGED AROUND SEATS. IF SCORED, REPLACE. IF TRASH OR DEBRIS, CLEAN AND RE-ASSEMBLE. |
|
M) FUNCTION SWITCH |
M) CHECK FOR ACTIVATION OF SWITCH BY MAIN VALVE CAM. ADJUST POSITION OF SWITCH ARM SO IT IS DEPRESSED AND SWITCH IS CLOSED IN THE STERILIZER MODE. |
|
N) ROCKER ARM |
N) VISUALLY CHECK FOR ROCKER ARM DEPRESSING PUSH ROD IN STERILIZE MODE. CHECK FOR CLEARANCE AND ADJUST (FLATTEN) CAM SHAFT IF NECESSARY. |
