Kenmore 795-71022.010 Inverter Error Codes, Requirement, Waiting Time, The number of, LED flashes

To reduce noise level, the piston stroke is slowly increased to full power during start up.

Step 1) Start up - Half stroke interval for first 1 second.

Step 2) Ramp up - Stroke increases every 0.8sec until maximum stroke length is reached

(about 1 min)

Step 3) CVCF interval - 180V / 60Hz

Step 1) Start up - Half stroke interval for first 20 seconds.

Step 2) Ramp up - Stroke increases until maximum stroke length is reached (about 1 min, 40 sec)

Step 3) VVVF interval - target voltage and frequency controlled by Control Board signals

There are 6 protection logics designed to protect the linear compressor system. When a failure is detected, the compressor will shut and will try to restart after a set period of time for each type of failure. The LED located on the inverter drive PCB will flash the appropriate code to indicate the detected failure. This code will continue to flash until the unit is disconnected from the power source.
