TROUBLESHOOTING TIPS
(For XLERATOR/XLERATOReco dryers with #40100, 40101 or 40102 Control)
For older open green circuit Controls with no LED light (#40100 or 40101), first test the sensor by unplugging it from the unit and
bringing it to another unit to test. If it works in the other unit, then proceed to test for proper motor operation. If motor works
according to procedure listed below, then the only item between the sensor and the motor is the Control itself.
For models with the LED light in the Control (#40102), or if Control has been replaced and LED is now in sensor:
IF LED LIGHT IS ON:
Place hands under sensor. If light stays on, you have a bad sensor. If light goes off but still no operation, check the wiring
against the schematic on the dryer. If both are OK, test for a defective motor.
IF LED LIGHT IS OFF:
Confirm power is going to dryer. Check wiring for loose, disconnected or improper wiring at Control, or replace Control.
IF LED LIGHT IS FLASHING IN CONTROL OR IN SENSOR:
Dryer is in lockout mode. Adjust the sensor range by turning the range adjustment knob on the Control counterclockwise
toward the “L” position (see below) and reset circuit breaker at electrical panel box.
IF DRYER RUNS CONTINUOUSLY:
Make sure sensor range is not set too high on Control. If so, adjusting the range counterclockwise toward the
“L” position may fix problem. If not, replace Control.
TO TEST FOR A DEFECTIVE MOTOR - Disconnect power to unit at electrical panel first.
Trace the wire that leads from the heating element to the Control (this will be attached to Terminal 3 or 4 on Control).
Disconnect that terminal end from the Control. Remove the wire attached to Terminal 1 on the Control (this is Terminal 2
on older open green circuit controls) and attach it to the terminal that was removed. Restore power and if motor is good,
it will start immediately.
NOTE: For 277V units, if the motor does not work using the previous test, you must visually check the heating element to
determine if the coils are broken. If the coils are INTACT, then the motor is most likely inoperable.
If the coils are BROKEN, then both the heater and motor must be replaced.
If problem cannot be resolved with the above, please call the manufacturer at
1-800-255-9235 and one of our trained technicians will be happy to assist you.
