Hi All,
I've have the erratic blower fan issue for a few years now, and I've finally gotten around to fixing it. I've remove the boards from the housing, and separated the horizontal board from the vertical board. I would like to replace the potentiometer since when I measure the resistance across the terminals, **** position 4 and 5 read open, and positions 1, 2, and 3 fluctuate. I don't seem to be able to separate the vertical pcb from the front trim plate. I hold back the tabs, but the temperature control ***** seem to be holding it in. Does any one know the trick to getting that board out? The pdf's that have been posted don't show how to replace the 4k7 potentiometer, they just talk about replacing it. Found this website describing how to remove the vertical board: https://www.benzworld.org/threads/w2...bulbs.2141945/ - you have to de-solder the temperature control pots.
Thanks, sincerely
-Jerry

PS. I was able to buy 5x 4k7 potentiometers from ebay for ~$7 with free shipping (https://www.ebay.com/itm/235043299378?var=534980590605). They seem to check out using my DMM - few ohms to 4.7kohms.
PPS. I just saw another post by RyanB from 8 years ago that said the white plastic hex inserts on the side that go into the temperature control wheel ***** pull out, and no desoldering is need. They didn't budge when I tried to pull on them. I didn't try very hard, so I can't verify. The desoldering was very easy, but pulling the wheels out would've been easier.
