Part Testing

Compressor and Capacitor Testing

With the unit 'ON' and controller calling for the

compressor to run, check amperage on 'red' wire coming

from the controller, see table below for values +/- 10%

Model #

178GDICE24FB/W

178GDICE49FB/W

Disconnect wiring from compressor, check resistance

from common to run and start windings. Resistance

should be found (Run to Start = (Runs to Common) + (Start

to Common))

Temperature will change resistance OHM valves

Check windings are not connected to ground by

checking for Ohms from each pin to the shell of the

compressor (Paint must be removed from case when

checking for grounding)

Visually check capacitor for any deformations or leaking

oil like fluids, replace if any is found

Discharge capacitor prior to testing, use a 20,000 ohm, 2

watt carbon resistor, caution resistor will be HOT during

discharge

Capacitor micro-farads = µF +/- 5%, replace if not within

range
