Buzzing transfer switch
Replaced my smoked transfer switch with the same model. Southwire/Surgeguard 41300. This is a basic model. My MH is a 2018 Class A Vista LX 27N. Replacement was pretty easy and straightforward. This was done last October just before it got put away for the winter. This spring brought it home and plugged it in to 15A circuit and it worked fine. First trip of the year it worked fine. Took a trip just after Labor Day and plugged it in and it buzzed like crazy. Ended up cycling the pedestal CB and after 4 or 5 tries and the buzz was gone. Was the ok for the rest of the week. Thought it was just a fluke or perhaps it had something to do with higher than normal pedestal voltage. Was reading 127V. Plugged in again at home after the trip and it was ok. Getting ready for another trip this weekend, plugged it in only for it to start buzzing again. Plugged and unplugged a few times and all was well. This is on a15A circuit reading 117V. Any ideas what’s gong on??????
All wires are tight and properly torqued. Bought a torque screwdrivers just for this purpose.
