VENT LIMT SWITCH L280 M/R
This VENT LIMT SWITCH L280 M/R is a brand new product
The VENT LIMT SWITCH L280 M/R is a replacement, dual function switch that fits most gas ignition systems. It combines the switch for both pilot light and vent controls into one device.
The VENT LIMT SWITCH L280 M/R mounts to the cabinet wall by the landing duct to prevent the fan from running when no cooking is occurring. The switch features a thermal de-rate function and provides an audible alarm if the furnace still has hot components, indicating that the venting system should be checked or serviced.
The VENT LIMT SWITCH L280 M/R should only be used on central forced air systems where a need has been identified as an odor concern or a humidity issues to the house. Williams Comfort Products recommends that the switch be installed so that the temperature setting is at least 10°F above the intended temperature setting for the house.
The VENT LIMT SWITCH L280 M/R is designed to be mounted in a "horizontal" position. The VENT LIMT SWITCH L280 M/R should be replaced if found to be inoperable, if it leaks, or if the internal components are found to be damaged.
The 250v VENT LIMT SWITCH L280 M/R by WHITNEY MFG. CO. is an operator limit switch that is compatible with most ventilator models. It has a single blade style plunger and bushing assembly, and features a bobbin type rotary switch with a solid brass stem and a molded-in safety switch cover.
The VENT LIMT SWITCH is used on all models of the L280/R furnace. This switch is designed to limit the air flow at the vent terminals. The air vent system is operated by a proportional pressure switch located in the blower case at the heat exchanger. On most models, the air vent system should be operated when the outlet plenum temperature gauge indicates 50°F ± 10°F (10°C ± 5°C) or less. This switch should not be adjusted.
