I want to start by saying hello to everyone I am new to the board. I do have a question and it has been discussed before but I could not find a solution. I have a Englander 25-PDVC that is about 5 years old. I have noticed that the room blower speed does not seem to go above number 3. If you start at number 1 and feel and listen to the blower speed there is a difference between 1-2-3 then no more gain in speed. I was wondering if anyone came up with a solution? I have cleaned and oiled the blower.
