THOR #15371
Fan under bed

Just took possession of a 2019 Miramar 37.1. So far so good.

While packing up, I hear a fan running under the back bed which sound like it is coming from the electrical fuse panel. Does this turn off or is there a way to turn it off?

Fan Noise


That noise is probably from your power center/converter. It is a normal function of the converter to control temps.

or it's your INVERTER external fan, installed by Thor, to minimize hot temps in the bay where the Inverter is located - it is powered thru a temp sensor, running the fan until the bay temp falls below it's set temp. Sometimes the fan seems to run non-stop, even when you know the bay is already cool.

to 'test' this sensor: apply a piece of ice to it temporarily and see if it shuts off the fan. The sensor is generally wired in the same area at the inverter, but sometimes part of a bundle of wires - usually a 'round' looking small device.
