E3 Fault High Pressure Switch Activation

This is stating that there has been a high pressure error on this system. This could be due to fan motor or air flow problems but it could also be an issue with the actual high pressure switch.

In this video I diagnose the High Pressure Switch to be faulty and I show you the steps I take to make that diagnosis. I also show you how I replace the actual switch and the steps involved.

Thanks for watching.
