Tom and Doreen Posted January 13, 2024 Posted January 13, 2024 I'm posting this in case anyone else encounters this problem: We were traveling back east from Hohenwald in a driving rain storm through GA and upon setting up at the campsite could not get the Truma furnace to heat; the error E 5 H was displayed on the digital display panel. The Truma documentation that I have did not list this particular error code. The furnace had been operating flawlessly prior to the rain storm so I suspected that the problem had to do with moisture preventing the furnace from igniting. I took a hair dryer and blew warm air up into the Truma exhaust vent to dry out any accumulated moisture and that fixed the problem. If anyone has a detailed description of the E 5 H error please post it here as I could not find a description online or in my documentation. 2 5 Tom & Doreen • 2023 Elite ll • Hull #1321 • 2023 Tundra Platinum Crew Max • Cheshire CT

Moderators topgun2 Posted January 13, 2024 Moderators Posted January 13, 2024 Nice creative and thoughtful approach - good work. But, THIS kind of thing probably shouldn't happen in the first place. I'd make sure that both Truma and Oliver Service know about it. Bill 3 2023 Ford F150 Lariat 3.5EB FX4 Max Towing, Max Payload, 2016 Oliver Elite II - Hull #117 "Twist" Near Asheville, NC

Tom and Doreen Posted January 31, 2024 Author Posted January 31, 2024 This is a follow-up to my earlier post regarding the E5H error. Truma did respond with the following description for the E5H code: "ionisation voltage recognized during standby mode. Could have been from a solenoid sticking for a moment due to moisture on the sensor, or a voltage spike". In my case I'm sure it was due to moisture as a result of traveling during heavy downpours. 3 4 Tom & Doreen • 2023 Elite ll • Hull #1321 • 2023 Tundra Platinum Crew Max • Cheshire CT
