Service Test 16 - Compressor Maximum Speed - Maytag Built-in Refrigeration Manual

Service Test 16 – Compressor Maximum Speed
This test will energize the compressor at maximum
speed. The compressor should have been off for at least
five minutes prior to this test. If the off time is not five
minutes, the short cycle protection within the compressor
controller will prevent operation until enough time has
elapsed.
The Service Test may time out (three minutes) before
sufficient time has elapsed for the compressor to start. If
the display changes back to this display (16 00) reactivate
the test.
Pressing the Power Interrupt Button will start the
compressor at maximum speed. The display will show
the current evaporator temperature on the fresh food side
of the display. If the compressor is working, this
temperature should quickly drop.
If the compressor does not eventually start after waiting
for at least five minutes check for the following
conditions.
JP10, pins 1 to 2, 2-2.5VAC this is the drive signal from
the Main Control Board to the Compressor Controller.
CN 05 pins 1 to 6, 230VAC, this is the output from the
compressor controller to the compressor.
