After about a year (second season using the stove) I had an issue with the stove stopping running during the heating cycle. The code "Alarm - Contact Lost". I Downloaded the complete service manual from the internet. It is more complete than the owner's manual that came with the stove. The on-line manual explained what the code meant and how to troubleshoot it. It said to check the 4-pin cable connection at bottom of circuit board. I did so, and it fixed the problem. Apparently the connection had come loose. The only comment I would make is that the explanation of how to address the code in the original owners manual would have been helpful. I then ordered the Parts Care Package to have extra parts on standby in case one goes out during the winter. The ordering process is very easy and I received the parts in just a few days.
