Chock & Level’s RV fault-finding sequence
Step-by-step troubleshooting guides and calculators for travel-trailer systems, from batteries and furnaces to towing weights and winterizing.
- For
- Travel-trailer owners troubleshooting common system faults
- Worth noticing
- The furnace sequence starts with loaded voltage and checks the sail and limit switches before reaching the control board.
Field notes
Guides are grouped into five systems—12 V electrical, propane appliances, water and tanks, towing and weights, and roof, seals, and seasons—with 30 guides listed. The furnace example begins with voltage measured while the blower runs, then checks the sail switch, limit switch, and electrode gap; the page says most cases are found by step three and places the control board at step six. The homepage describes the material as based on manufacturer service manuals.
