electronic control. Is line to neutral
voltage being applied?
3. Disconnect the wiring harness
from the compressor controller
and measure the voltage drop
between the two wires in the
harness. Does the meter read line
to neutral voltage?
1. Check voltage at compressor.
2. Defective compressor or
compressor controller.
1. Is there something blocking the
fan blade?
1. Check the light bulb with an
ohmmeter. Is the bulb good?
1. Connect a low side gauge to the
processing tube on the
compressor. Is the pressure in a
vacuum or lower than normal?
1. Check error code.
1. Defective timer.
Yes. Set control from 1 to 7
No. Go to step 3.
Yes. Replace defective electronic control.
No. Defective wire harness.

1a. No voltage. Defective wire harness.
1b. Voltage. Replace compressor controller.
2. Replace compressor controller. If problem
is not corrected replace compressor.
