Comp Circuit Diagnosis: If Comp does not start, check for 115VAC at K1 connector pin #10 gray (GY) wire to any white (W) neutral wire. If 115VAC is not present, CB is bad and must be replaced. If 115VAC is present, check for 115VAC at Comp relay coil

gray (GY) wire to any white (W) neutral wire. If 115VAC is present, and Comp is not on, check for 115VAC at Comp relay orange (O) wire to Comp relay red (R) wire. If 115VAC

is present, Comp relay is bad and must be replaced. If 115VAC is not present, check for 115VAC at Comp relay red (R) wire to any white (W) neutral wire. If 115VAC is not present, electronic unit is bad and must be replaced. If 115VAC is present, and Comp

is not on, remove the electronic unit to access Comp terminals. Next, check for 80VAC from each Comp terminal to ground. If 80VAC is not present, electronic unit is bad and

must be replaced. If 80VAC is present, check Comp continuity.

VSC COMPRESSOR MODULE

The compressor adjusts its speed in steps to any in-creasing or decreasing cooling demand, within the minimum and maximum speed limits. If the thermo-stat switches the compressor "ON": After a 60-minute running time, the speed will increase stepwise every 15 minutes, depending on the latest speed used, until the maximum is reached. If the thermostat switches the compressor "OFF": After each "ON", the compressor either restarts with lower speed steps than the recently used, until the minimum is reached, or increases its speed stepwise, after a new 60-minute running time.
