TROUBLESHOOTING
Optional water fill kit.
Close door.
Close door and set timer
to 30 minutes
Look for temperature rise on
the dial temperature guage
Water fills to high water probe
Power light illuminates.
After 15 seconds timing light illu-
minates and fan operates
Heats to 200 + degrees in
22 +/- 5 minutes
High water probe
Control board
Water fill solenoid valve
Incorrect wiring
If no power light or timing
light, but fan operates;
check door switch
If no power light or timing
light, but fan operates;
check control board
If fan does not operate with
power light and timing light
illuminated, check items below
Start capacitor
Internal thermal protector on
fan motor
Fan Motor
Control board
Incorrect wiring
Hi-limit 2 (auto reset)
Water level board
Contactor K3
Probe measures open to ground
without water. Short probe wire
to ground to simulate water.
Substitute to test
Valve is normally closed.
When water is below High
probe, 24vac is applied to coil
of valve and it opens.
When water reaches high
probe, coil de-energizes.
Check per wiring diagram
Measure from J9 pin 1 to 2.
12vdc with door open, zero (low)
voltage with door closed. If volt-
age is not zero, check door
switch, door magnet,
light & timer board, wiring.
Substitute to test
Standard test
Measure black to white motor
leads. 35 +/- 20% ohms
Measure orange to brown motor
leads. 35 +/-20% ohms. Red to
blue 42 +/- 20% ohms
Substitute to test
Check per wiring diagram
Measure for continuity
normally closed
Red light indicates power to
board. Bypass to test. Disconnect
wire to L1, move wire from NO-2
to NC-2, remove wire from H and
NO-1 and jumper these two
wires together.
Verify 24vac across K3 Coil.
Measure amperage through
heater wires and compare to
chart on Page 6.
