PROBLEM
PROCEDURE READINGS
The meter should read “zero” resistance
(contacts closed). If it reads anything else,
replace the timer.
The meter should read “infinity” (contacts
open). If it reads anything else, replace
the timer.

the timer.
The normally closed switch should show
continuity (0
Ω
).
TIMER (continued)
NOTE: The production timer
(Paragon) has a 10 hour
cumulative run time with a 21-
minute defrost duration.
The service replacement timer
has an 8 hour cumulative tun
time with a 21-minute defrost
duration.
DEFROST MODE
1.Set the ohmmeter to the
Rx1 scale and zero the
meter.
2.Touch the meter probes to
timer terminals PK and BK.
3.Touch the meter probes to
timer terminals PK and OR.
COOLING MODE
1.Use the screwdriver and
manually advance the timer
¼-turn.
2.Touch the meter probes to
timer terminals BK and OR.
3.Touch the meter probes to
timer terminals PK and BK.
Touch the meter probes to
the overload terminals.
The PTC relay cannot be
tested. To determine its
reliability, unplug it and use
the following procedure to
check it:
1.Check the R and W wires at
the compressor for
120 VAC.
2.Check the overload relay to
make sure there is continu-
ity through it.
3.Test the capacitor.
4.Use a test cord and start
the compressor. If it starts,
and the components are
operating, the PTC relay is
defective.
Unplug the capacitor from the
relay, discharge it and touch
the probes to the terminals.
OVERLOAD PROTECTOR
The meter should peak and then drop.
Reverse the test probes on the terminals
and the same results should occur.
