Description
The Nordyne 626611 is a factory-replacement automatic-reset limit switch engineered to protect Nordyne heating systems from dangerous overheating conditions. When supply-air temperatures exceed the upper threshold, the switch opens the control circuit and shuts down the burner; once temperatures fall back to a safe level, the switch automatically resets — restoring normal operation without requiring a manual reset.
