How i can use westpoint aircoditioner model wsz30-4krt as heater?

This is not a make that we know in North America and appears to be an African make, Tanzania?

The reasons for over heating compressors are Condenser fins blocked with fluff.

The reason for a compartment not cooling is lack of refrigerant gas or blocked condenser fins.

Clean the condenser with a brush and a vacuum. If that doesn't fix it, you need a Service Call or a new one (depending on age and condition).
