I went to start up my Mt. Vernon AE for the season and my wall thermostat went into StartUp mode, but soon thereafter threw an error code Max Drop Tube Temp (problem 1). In addition to that, the convection blower fan (the one that blow hot air from the front) spins itself to full speed and stays that way (problem 2).
I've done just about all the work on this unit for years so I'm pretty familiar with the parts and how to repair them. The local dealer has a back log of technician appointments that extends almost to the new year. So I'm looking to see if anyone has heard of this combination of errors and a possible solution.
