It appears the low limit switch is not functioning. I replaced it in February 2018 and it's showing the same symptoms (persistent low limit error). If I use a jumper between the two terminals (a trick you taught me), it runs fine. Is it time to replace the switch again?
The one I ordered last time was this one: https://www.eastcoasthearth.com/products/ceramic-low-limit-mounts-on-exhaust-housing-switch-for-us-stove-5660-hi-quality-long-lasting-052
as always, thanks,
