Overview
Genuine SBI replacement f125 limit switch retrofit kit for the Osburn Hybrid 45, Drolet ECO-45 and the other models listed below.
This kit retrofits an F125 limit switch (thermodisc) in place of the original F-140 heat-sensor switch, which mounts on the exhaust (combustion) blower housing of these 45-series pellet stoves. The stove's control board uses this switch to confirm the stove is up to temperature. A failed switch can shut the stove down or stop it from running normally.
- Part number: SE09243
- Type: F125 limit switch (thermodisc), retrofit for the F140 (kit SE09242)
- Location: exhaust (combustion) blower housing
