The replacement switch was shipped the same day and arrived in 2 days. The replacement switch did not look exactly like the original part – but I expected that since the original unit/part was built over 30 years ago. Nonetheless the switch fit perfectly and installation was easy and took under 30 minutes - with most of that being the time to pull the unit out from the cove, removing the back panel and carefully labeling the wires for installation. Fixed the problem. Burner heats normaly through the settings.
