PARLOUR PELLET 3000

The Trim/Feed adjustment on my Parlour Pellet 3000 does not change the speed when adjusted. Manufactured in 2002. Any ideas of what could be causing this issue would be appreciated.

That is an old control and the semiconductor and component characteristics can change with age so it may not work as well. If that has the 8 pin connector it is still available here:

The controls with the 10 pin connectors are no longer available, but can be updated to a new control board:

Don, Thank you very much for the reply. I will check it out.
