Hi Hope this is the correct thread. We have a 1989 300 Weekender with the original Cruisair 10000 BTU AC system (three knob control panel).
I flushed the system with Barnacle Buster and replaced the wet section of the circ pump. I did not re-prime the pump prior to turning it on (I know - I calling myself the same names), and it ran - with a loud noise - four times I switched it on and off, until the unit will not start at all now. I've done enough research to know there could be a fuse (not normally on a single system installation), possibly a open no flow relay, or a open pressure switch relay.
My question is, are these relays re-setable - can I reset them (after re-priming of course) . Thanks for any help
