SO I had to replace micro switches in the handle this morning because error code 112 was showing. I had found that a previous person disconnected one of them and needed to be replaced. I discovered that the switches I put in were good but one of the wire assembles tripped every time I connected it. Like tripping a breaker. I did switch sides and confirmed it was in the wiring not the switches. They said to check the speed switch but what is that? It is not listed on parts site that I could fined.

Can anyone help.

Thanks
