S-7 CHECKING CONTACTOR AND/OR RELAYS

HIGH VOLTAGE!
Disconnect ALL power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause property damage, personal injury
or death.

The compressor contactor and other relay holding coils are
wired into the low or line voltage circuits.  When the control
circuit is energized, the coil pulls in the normally open
contacts or opens the normally closed contacts.  When the
coil is de-energized, springs return the contacts to their
normal position.

NOTE: Most single phase contactors break only one side of
the line (L1), leaving 115 volts to ground present at most
internal components.

1. Remove the leads from the holding coil.

2. Using an ohmmeter, test across the coil terminals.

If the coil does not test continuous, replace the relay or
contactor.

S-8 CHECKING CONTACTOR CONTACTS

WARNING

Disconnect ALL power before servicing.

SINGLE PHASE:

1. Disconnect the wire leads from the terminal (T) side of the

contactor.

2. With power ON, energize the contactor.

WARNING

Line Voltage now present.

3. Using a voltmeter, test across terminals.

A.  L2 - T1 - No voltage indicates CC1 contacts open.

If a no voltage reading is obtained - replace the contactor.

L1-L2, L1-L3, and L2-L3 - If voltage is present,
proceed to B. If voltage is not present, check breaker
or fuses on main power supply..

B.

T1-T2, T1-T3, and T2-T3 - If voltage readings are not
the same as in "A", replace contactor.

HIGH VOLTAGE!
Disconnect ALL power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause property damage, personal injury
or death.

1. Disconnect wires leads from terminals 2 and 4 of Fan

Relay Cooling and 2 and 4, 5 and 6 of Fan Relay Heating.

2. Using an ohmmeter, test between 2 and 4 - should read

open. Test between 5 and 6 - should read continuous.

3. With power ON, energize the relays.
