A. The display reads “Exhaust High Limit Fault”. (Refer to page 51)
The temperature in the tumbler is above 220º F (104º C) or follow
Steps #1 through #4
.
1. Check for voltage (24 VAC) at the computer on the J5 connector from pin 1 to ground. If no voltage
is present, either you have a poor connection at the J5 connector or the computer board is faulty. If
voltage (24 VAC) is present, proceed to
Step #2
.
2. Check for voltage (24 VAC) at the J12 connector pin 3 to ground. If no voltage is present, there may
be a poor connection at the J12 connector or a break in the wire going back to the J5 connector. If
24 VAC is present, proceed to
Step #3
.
3. Check for voltage on the J12 connector pin 4. If no voltage is present (24 VAC), check tumbler
thermostat reset. If popped, push in to reset. If thermostat does not reset, then replace with new
thermostat. If thermostat has not tripped, then check for poor connection in wire. If voltage is
present, proceed to
Step #4
.
4. Check for voltage at the J5 connector pin 2 to ground. If no voltage is present, check for a loose wire
between the J5 connector and the J12 connector.
B. The display reads “Burner High Limit Fault”. (Refer to page 52)
1. Indicates the tumbler hi-limit has tripped.
2. Check for a block or restriction in the exhaust.
3. Make sure the exhaust is properly sized.
4. Make sure location has adequate make-up air.
5. Check for voltage (24 VAC) at the computer board J4 connector pin 3 red wire 31 to ground. If no
voltage (24 VAC), check for a loose connection or change the computer board. If voltage is present,
proceed to
Step #6
.
6. Check for voltage at the J11 connector pin 2 to ground. If no voltage (24 VAC), check for a loose
connection in the wire, or check the oven hi-limit reset. If it has tripped, push in to reset.
C. The display reads “Bad Exhaust Temp Probe”. (Refer to page 55)
1. Check for a loose connection at the computer J3 connector to temperature sensor probe. If
connections are fine, next change the temperature sensor probe. If the display still reads “Bad
Exhaust Temp Probe,” change the computer board.
D. The display reads “Sail Switch Open Fault”. (Refer to page 52)
1. The sail switch has opened while dryer is in the heating mode.
2. Check for block or restriction in the exhaust.
3. Make sure exhaust is sized properly.
4. Clean the lint screen.
