Contact us, we may be able to help walk you through a troubleshooting process, even if you’re still operating with the original Intellitec system. We often tell potential customers that the Waiter ECC system will not repair a faulty A/C unit.
Verify that you have 110 Volts to the A/C units, coach breakers, pedestal breakers, generator breakers, etc.
Do the blowers run if placed in FAN HI or FAN LO?
Verify the 120 volt circuit breakers in the motorhome are not popped (turn them off, then back on again)
If on shore power, verify the pedestal breaker isn’t popped. Do other appliances work.
If on generator power, verify that both 120 breakers on the generator or not popped.
If its just one A/C unit that doesn’t run but the other is OK, you can swap the FRONT / REAR plugs on the control module to see if the problem stays with the same unit. Don’t forget to switch them back.
