11 Measurements and Adjustments
11.1. Component Controlling
11.1.1. Compressor:
It pumps the refrigerant absorbed from the cooling system to
the condenser. Basically it is consist of a cylinderpiston system
and an electric motor. Electric motor creates the rotational
motion which turns into vertical motion at cylinders to create
exhaust & compression.
Possible compressor defects:
• Short circuit / bobbin fault
• Compressor locking
• Low compression pressure
Check the relay connections
If the relay connections are open circuit they must have
exchanged.
Normally relay resistance should be between 10 and 30 (You
should disconnect capacifor before measurement)
Check the compressor windings. If there is any open or short
circuit the compressor must have exchanged.
