Need replacement parts for this unit?
Furnace designs over the last 10+ years have been required to have 2 or more of these manual reset limits inside the furnace to cover safety concerns and prevent flame rollout conditions.
This new line of limit switches complements our existing line of 1/2" automatic (3F11) fan controls & (3L11) limit controls and are offered in a broad range of temperature limit cut-outs to cover most heating applications.
This item is cost-prohibitive to ship on its own but is available to ship with orders over $200.
