So I have a 2017 Caldera Paradise Martinique not heating up. It has power, no tripped breaker, and I have isolated it to the board. The fuse on the main board is fine. The LED for the heater does not come on. So, where do I start with troubleshooting? I am very handy with tools to include my voltmeter and resoldering board components if I have to. I even wish I could get a repair manual but, I am sure they are only available to factory authorized service reps.
