transformer fan

The transformer fan directly under our refrigerator on our 2005 surveyor 29 shuts off and on constantly and is quite annoying. I can turn a light on and it comes on and might stay on for a few seconds then kick off and is very loud. Would love input

I can't be sure but can only guess that this fan is triggerd by heat. Could be a faulty thermal sensor in the circuit. Also not sure that they aren't supposed to just run all the time and there is something wrong that is giving it intermittant voltage thus the starting and stoping. Someone here should be along soon hopefully with more info.

Have you battery checked. If it is original, it's probably bad and turning on a light causes enough current draw on the converter to kick the fan on for cooling. My guess is battery. Test by unplugging shore power and turning on a couple of lights. See if they last more than an hour or so.

It's common for the converter fan to kick on when it see's a load. One light shouldn't normally do it but a few will. I agree with testing your battery(s) first to make sure there's not a problem there. You can change the noisy fan out with a much quieter model. Just get the info off the fan and search the net for a quiet replacement. Mouser Electronics is one place to look. Look for the lowest dB rating you can get for the SCFM you need.

The fan on our last pup used to come on occasionally. I've never heard the fan on our Surveyor. Maybe I'm just getting old and hard of hearing! HA! But coming on that often and at the slightest provocation doesn't seem right.
