About four weeks ago had a lot of smoke coming out of our stove. We started taking it apart to figure out what the problem was. There was a lot of creosote build up in the bottom auger. We ordered new auger, got them aligned started up E2 followed by E1. We noticed one motor wasn't running, so ordered a new one. Replaced that still getting same codes. The blower seems to be running. Not sure how to check the vacuum switch. This stove was in our house when we bought it, so we are still learning. Any suggestions would be helpful.
