As we’re getting our boat up to speed, we’ve been encountering some fickleness in our Webasto thermostat controller 1320415A. When I turn it on, I have to fiddle with the cover in order to get it to stay on. I took the cover off and checked the connections, and the issue seems to be with the on/off switch itself. When I futz with the switch, the indicator light will go on and off. Short of replacing this unit entirely (ebay has it for $150, buyer always beware), has anyone dealt with a similar issue? What was the fix, if any?

If you can get to the soldered connections on the rocker switch, you may be able to de-solder it from the unit.
The switch should have its electrical values printed on it.
