Hey guys first time poster here hope I posted in the right area. I have a breckwell WH-23FS my grandpa had it for years he passed away about 4 years ago. So I have it now. It's about 20 years old. Well here in the last couple of years. It wont drop pellets automatically. I have to manually feed it for about 20-25 minutes then it will automatically feed them. And it will run until I shut it off just fine. Then I have to do it all over again the next time I start the stove. Any suggestions?
