Introduction

What you need

Step 1

              Compressor Relay
  • The Marine Air Passport II Air Conditioning unit uses a mechanical relay for the compressor. The relay will eventually fail resulting in the contacts welding together and the compressor and water pump running continuously, or failing to run. Replacing the relay is a simple fix.

Step 3

              Install the new relay

The original relay is discontinued. An acceptable substitute is a Potter and Brumfield T90S1D12-5 available at Digikey Electronics. Solder into place.
