OEM vs. Generic

This is a factory-calibrated safety device. OEM B1370145 trips at the exact temperature and uses the correct terminal and bracket configuration your furnace expects. Substitute switches with the wrong set point or footprint can nuisance-trip or, worse, fail to protect. For a safety control, OEM is strongly recommended.

Why Replace It

A tripped or failed rollout switch causes a no-heat, hard-lockout condition. Never simply jumper it — a trip indicates a real combustion or venting problem that must be corrected before installing the new switch.

Install difficulty: Easy to Moderate. About 15 minutes for a technician: remove two screws and the spade terminals, then mount the new switch. Because this is a combustion safety, professional diagnosis of the root cause is recommended.
