Earlier models had the fuse...Some were inside the box and were an automotive type in-line with a rubber fuse holder that had a cap that was removed to access the fuse...

Newer models do not have a fuse and must be protected by a fuse or breaker in the main panel...and you could have both the fuse inside the PR3X, plus the breaker in the panel...

I see newer models like in the Training PDF I linked do not have a fuse...

Hi Russ~

First question...Did you check the fuse in the pump relay ?

Here's a troubleshooting PDF for Cruisair pump relays: ** you don't have permission to see this link **

 

Let know how it works out...

This week my AC's were kicking off.  Found pump not running.  Tested motor and it not running.  Replaced with spare pump.  Turned on rotary switch and checked for water circulation - none.  Hard wired pump and it came on and Units working.  I have a Cruisaire PR3X-3 Pump Relay Station.  Do I replace the board, or just the Triacs?  How do I find which one, or one's to change?
