Maintenance

Resistance Test

1.With no power, remove the leads from the compressor terminals.

2.Touch the leads of an ohmmeter to terminals C-S, start windings and C-R, run winding.

If either winding does not test continuous, replace the compressor.

Testing capacitance

capacitance (MFD) = 2650 X amperage voltage

Note: Replace the capacitor if the value obtained is not within 10% of the rating printed on the capacitor.

Ground Test

WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.

With no power and compressor leads removed:

Set an ohmmeter on its highest scale. Touch one lead to the compressor body (clean point of contact, as a good connection is a must) and the other probe to each compressor terminal in turn. If a reading is obtained, then compressor is grounded and must be replaced.

If the voltage, capacitor, overload and motor windings test fail to show the cause for failure:

1.With no power, wire a test cord to line voltage (Line & N).

Note: The wire size of the test cord must equal the line size, and the fuses in the test line must be of the proper size and type.

2.Connect a good capacitor of the right MFD and voltage rating into the circuit as shown in Figure 40.

Figure 27. Test cord connections

3.Carefully apply line voltage.

a.If the compressor starts and continues run, the cause for failure is somewhere else in the system.

b.If the motor fails to start - replace. Since all single phase compressors are of the permanent split capacitor design the high and low side pressure must be approximately equal or the low torque compressor may not start.

Indoor Coil and Air

Thermistors

1.Remove the Indoor Coil Thermistor leads from the circuit board.

2.Check the resistance of the Indoor Coil Thermistor against the table on the next page. The leads of the ohm meter will need to contact the ends of the thermistors that connect to the board.

3.Replace the Indoor Coil Thermistor if it does not test as above.

Outdoor Coil and Air

Thermistors

1.Remove the outdoor coil thermistor leads from the circuit board.

2.Check the resistance of the outdoor coil thermistor against the table on the next page. The leads of the ohm meter will need to contact the ends of the thermistors that connect to the board.

3.Replace the outdoor coil thermistor if it does not test as above.

Heater Assembly with Power OFF to the Unit and Heater

1.Remove the heaters in question and visually inspect the element for broken condition. Refer to the disassembly procedures for information on disassembling the heater.

2.Test the thermal fuse (one time fuse). If open, replace the heater assembly.
