The compressor(s) will not start
Jan 11, 2018

When my unit is connected to a suitable electrical system, the compressor and condenser fan are not connecting.

Check these possible causes and solutions:

A blown fuse in the main line or in the compressor circuit

→ Locate the source of the overload and replace the fuse.

A defective refrigeration switch.

→ Replace the defective switch.

The refrigeration circuit has a defective power relay.

→ Replace the defective part with an equivalent relay.

The off/on, high/low or pressure (if equipped) has cutout.

→ To fix this, push the button on the individual controls to reset. Also, check the cause of the pressure cutout.
