  • Webasto Blower Runs Continously

    Posted by Archived on January 25, 2022 at 7:12 am

    Greetings!

    My Webasto unit functions well, with a recent exception. The blower motor runs continuously after the unit is shut down. Only after unplugging the power supply would the blower motor stop running.

    Any ideas?

    Morning Colt, One of the failure modes of the silver Control Unit, the brain box that runs the Webasto burner is failure to shut down after the end of the cool down cycle. Purchase a new one to solve the problem.

    If you have a 12 vdc burner, red writing on the control unit, I have a rebuilt control unit for $500. Or I have a new Aqua Hot designed unit that is all solid state for a mere $990. I can ship today and will pay ground shipping from the Houston, TX, area.

    Rudy,

    I bought your black box and have 2 issues recently. 1, the heating unit never turns off, only goes from high to low flame and then back again. Also, you said it would by-pass the coach circuit breaker but I have had that trip twice when I turned it on during a very cold morning. The bays are getting up to 70 degrees when it’s 30 degrees outside as the inside blower shuts off at the right temp but the circulation continues and heats up the bays. Good for the bays but bad for never ending fuel useage.

    Thank you, Rudy.

    I have a 24v system. I would prefer to purchase from you if you have the controller. Please let me know.
