My furnace quit working. Looking online I found a site that advertises experts who can help. Offhand I don't remember the site but I did get good advice and I think it cost me 33 bucks. Way cheaper than a visit from the furnace folks during the coldest weather we have had on Whidbey for at least a year. On the weekend.
But the reason for this post is that not only did I get good advice about the problem I also got a lesson in good quality control. The problem with the 17 year old furnace was a bi-metal switch called a "Flame Rollout Sensor". In any case there are two of these switches. They are easy to reset but I was told that if one needs to be reset and there is a flame present then the switch is failing. So I was told to buy two switches because if one failed the other one will fail soon. So I bypassed one switch and the furnace started working again. Two days later the second switch failed. That is some great quality control. After 17 years of operation the switches failed within two days of each other. I am impressed. It's a good thing I took the expert's advice and ordered two switches.
