Capt Mike Posted March 20 Share Posted March 20 Looking for this particular combo switch for a Fantastic vent on a 2008 38 PDQ. The rheostat for the fan speed is working only on full ahead. Tried to remove the knob without any luck. Any ideas would be much appreciated. Link to comment Share on other sites More sharing options...
Ed Adair Posted March 20 Share Posted March 20 The knob on mine has a set screw on the side of it. Link to comment Share on other sites More sharing options...
Capt Mike Posted March 20 Author Share Posted March 20 From what I can see on the set screw, it’s either an Allen screw or a torx? I can’t get anything in there to loosen it. Link to comment Share on other sites More sharing options...

Bob Danny Posted March 20 Share Posted March 20 Could it be the contact on the fan opening, mine where dirty and corroded, after cleaning it worked fine. Link to comment Share on other sites More sharing options...
Capt Mike Posted March 21 Author Share Posted March 21 I’m going to get some new Allen wrenches and get the rheostat replaced. Thanks for all the help folks!! Link to comment Share on other sites More sharing options...

Some of the smaller sizes are in 0.5 mm increments . . . that's 20 thousandths! Make sure you have a tight fit to keep from stripping out the head Try spraying tuner cleaner inside the potentiometer / rheostat first. - bob Link to comment Share on other sites More sharing options...
