Product Overview: The Atwood 66574 is an automatic leveling controller for fifth wheel RV electric jack systems. It manages paired jack operation (front and rear pairs) and can perform automatic leveling sequences when programmed on the vehicle. The controller features sensor technology for position monitoring, communicates with a separate keypad via dedicated cable, and uses DIP switches for configuration. It interfaces with the RV's leveling jack system to extend and retract jacks based on user input or automatic leveling programs. Common failure mode involves microprocessor failure, which is unrepairable due to locked firmware.

Send your keypad AND controller (see diagram) and we will test them to isolate the problem to the keypad, controller, or wiring/jacks (minimum $75 checkout fee may apply). Excessive burn damage or corrosion will result in additional costs.
Common Failures
Several units were returned due to non-operational control boards, primarily involving microprocessor failures. These include issues where keypads failed to power up or ceased communication, and the inability of jacks to extend or retract. Such problems can arise due to defective microprocessors. Units with failed pre-programmed microprocessors may not be repairable if replacement components are unavailable.
Repair Approach
Many units that passed diagnostic tests showed no faults in our facilities. Some units were tested extensively but yielded "No Fault Detected" results, and various issues were determined to be non-replicable under our test conditions. Customers were provided guidance on proper configurations as per the operation manuals.
Testing & Quality
Units underwent rigorous checks, including Level 5 Testing and burn-in tests with various fixtures. In cases where no defects were found, units were returned unchanged. Ensuring units operate as designed is a priority before returning to customers.
Replacement Options
For cases where units were deemed beyond economic repair, customers were offered information on replacement options. We recommend following the operation manuals closely and consulting with our team regarding available control unit options if existing setups require replacement.
