COMPONENT TEST PROCEDURE METER READING
PTC START The PTC Start Relay cannot be
RELAY tested. To determine its reliability,
use the following procedure:
1. Measure the R and W wires at
The compressor for 120 volts AC.
2. Check the overload relay to make
sure there is continuity through
It. (Use the previous test proced-
ure.)
3. Test the run capacitor. (Use the
following test procedure.)
4. Use a test cord and start the com-
pressor. If it starts, and the pre-
ceding checks are okay, the relay
