Issue

Unit will not operate

Troubleshooting

Applies to

• Westinghouse Split System Air Conditioner
• Kelvinator Split System Air Conditioner

Solution

Please check the following:

Is there a power failure?
Has a switch been turned off, a circuit breaker tripped or a fuse blown?
Is the timer operating?
Are the batteries used in the remote controller exhausted?
Are the batteries used in the remote controller loaded properly?

Auto-restart function

For units with Auto-restart feature, when the power restores, the unit restarts automatically with all the previous settings preserved by the memory function.

For the units without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit will flash for 1 second. To restart the operation, push the ON/OFF button on the remote controller.

Note: Operation is delayed after restart

To prevent blowout of the fuse, the compressor will not operate while the protection circuit is working for about 3 minutes after sudden OFF/ON operation of the power supply, this is normal operation and designed to protect the compressor.
