Honeywell High Pressure Switch
High-limit pressure switch for sidewall vent and high-efficiency furnace applications.
Overview
A higher-set Honeywell pressure switch designed for furnaces with sidewall venting or high-static inducer systems. These switches trip at a higher negative pressure, making them critical for high-efficiency condensing furnaces. If your high-efficiency furnace is locking out with pressure switch codes, this may be the specific replacement you need.
+ Pros
- Precise pressure setpoint for high-efficiency furnace applications
- OEM quality with consistent manufacturing tolerances
- Includes gasket and mounting hardware
- Critical component for condensing furnace operation
− Cons
- Higher price point than standard pressure switches
- Specific pressure rating must match your furnace — no universal option
- Some models have long lead times if not in stock
Who It's For
Homeowners with 90%+ AFUE condensing furnaces that use a higher pressure switch setpoint. These are common on Lennox and Carrier high-efficiency models.
Who Should Skip This
Standard 80% furnaces don't use high-pressure switches. If you have a standard furnace, get the regular Honeywell pressure switch instead.
Compatibility
High-efficiency condensing furnaces requiring higher pressure switch setpoints
Bottom Line
If your high-efficiency furnace needs a high-limit pressure switch, this is the OEM-grade replacement. Check the pressure rating stamped on your existing switch before ordering — they're not interchangeable.
