LECTRICAL HECKOUT
1. Be sure the unit is disconnected from the power source. Remove the compressor electrical box cover. Check
for obvious damage and loose wires.
2. Disconnect the fan motor leads. Since capacitors store energy, short the capacitor with a screwdriver. This will
prevent shocks.
3. Disconnect the compressor terminal wires.

VERLOAD HECK
Using a volt-ohmmeter check the continuity across the overload, contact #1 and # 3. If none, wait for unit to cool down
and try again. If still no continuity, the overload protector is defective and should be replaced.
