Model 596.70129891 11,800 Btu

Due to a possibility of personal injury or property damage, always contact an authorized technician for servicing or repair of this air conditioner.

Refer to Service Manual for operation, disassembly, testing, and troubleshooting information.

Refer to Repair Parts List 20112001 for part number information.

! CAUTION

All safety information must be followed as provided in Service Manual for this device.

! WARNING

To avoid risk of electrical shock, personal injury, or death, disconnect power to unit and discharge capacitor through a 10,000 ohm resistor before servicing, unless testing requires power. Wires removed during disassembly must be replaced on proper terminals to ensure correct grounding and polarization.

Illustration Component Test Procedure Results

Compressor Check resistance of compressor windings: Ohmmeter indicates <10 but >0 Attach ohmmeter between winding C and S: Ohmmeter indicates <10 but >0 Attach ohmmeter between winding C and R: Ohmmeter indicates open on each terminal. Check compressor for grounds: Attach one ohmmeter lead to compressor case. Attach second ohmmeter lead to C, then S, then R terminals on compressor:

NOTE: See Testing Procedures section of Service Manual for additional compressor tests.

Fan motor Check fan motor for grounds: Ohmmeter indicates open on each lead. Capacitor Attach one ohmmeter lead to fan motor case. Overload protector Attach second ohmmeter lead to each fan Ohmmeter indicates continuity between all motor lead, one at a time: windings.

Check for continuity of fan motor windings: Attach one ohmmeter lead to common fan motor lead. Attach second lead to remaining fan motor leads, one at a time:

Resistance (highest scale), with power removed.

Discharge capacitor and disconnect all attached wires.

Attach ohmmeter leads between C terminal

and H terminal on capacitor: Indicator swings to zero and slowly returns

toward infinity.

Reverse leads on C and H terminals: Indicator swings to zero and slowly returns

toward infinity.

Attach ohmmeter leads between C terminal Indicator swings to zero and slowly returns and F terminal on capacitor: toward infinity. Indicator swings to zero and slowly returns Reverse leads on C and F terminals: toward infinity.

Resistance Continuity Ensure temperature of protector is below Open 142°F ±16°F (61°C ±9°C). Check resistance Continuity across leads: Heat thermostat to 293°F ±9°F (145°C ±5°C): Cool thermostat to 142°F ±16°F (61°C ±9°C):

Electronic control Check for opens in wiring between circuit board Continuity is indicated between circuit board terminals and component connections. terminals and component connections. LINE 2 LINE 1 COMP LOW MED HI

See wiring diagram for specific wire terminal positions. If continuity is not indicated, replace wiring before replacing electronic control board.
