If anybody has a source or a spare one let me know and we can make a deal?
Check with RPARTS.COM - RPARTS.COM
they also have the same module pictured on amazon Canada. I bought 200 of them and sold all but the ones I use to loan out. EBay has used ones and Frigoboat has their own replacement. Be careful these modules are either 12 volt only or 24 volt only. Replace module you might get another 10 years out of the system for less than $200.
Have you run the standard tests to confirm the module is bad many techies and salesman think the module and system can be condemned by using a volt meter.
Troubleshooting 4 pin modules consists of the following:
1. Place jumper wire across thermostat terminals, Compressor still does not run.
2. Disconnect black fan wire from electronic module, Compressor runs replace fan. Compressor still does not run after fan ground wire is disconnected. If one of the 10 transistors in this fan fail it can cause module to prevent compressor from running.
3. Run correct size and correct polarity fused jumper wires direct from a fully charged battery
to module in order to bypass all boat’s wiring
. Volt meter readings are of no value, Compressor still does not run electronic module needs to be tested on another unit.
