Engineered as an exact-fit replacement for Carrier model CP48P548P507510CP, it matches the original trip setpoint, port size, and electrical terminals so it seats exactly where the factory switch did. A failed or stuck switch causes ignition lockouts, no-start conditions, or repeated short cycling, usually accompanied by a specific fault code, since the control board will not advance without a valid switch signal. Installing the correct OEM switch with the proper pressure rating clears nuisance lockouts and restores safe, reliable startup. This is a relatively easy repair: disconnect power, remove the hose and electrical leads, unscrew the old switch, and install the new one in the same orientation, roughly 20 to 30 minutes. Confirm the sensing tubing is free of condensate before testing. Genuine Carrier quality guarantees an accurate trip point.
