Introduction
In this guide, I'll show you how to replace the fan wheel for the recirculating air (34000-04700) on the Truma heater.
This wheel transports the recirculating air into the heater and ensures that the air is distributed throughout the vehicle via the ducts.
This replacement can be necessary, for example, if it is making noises or is damaged. If the performance of the recirculating air motor decreases, or if the power consumption in ventilation mode is significantly increased.
