Overview

This OEM refrigerant pressure switch set — high-pressure switch (part 1184656) and low-pressure switch (part 1184655) — protects the compressor in your Tempstar TSH536HKA200 by breaking the 24V control circuit when system pressure leaves safe limits. The high switch opens on excessive discharge pressure (blocked condenser, failed fan, overcharge); the low switch opens on loss of charge or restricted flow. A failed or tripped switch commonly causes a unit that won't start or short-cycles on a safety lockout.

Compatibility

Installation Guide

Safety First — Disconnect power; verify zero voltage with a multimeter.
Access — Remove the service panel to reach the switches on the refrigerant lines.
Document — Photo the 24V wiring and which switch mounts on the high vs. low line.
Remove — Disconnect the leads and unthread the switch from its Schrader fitting (a small refrigerant burp is normal on quick-connect types).
Install — Thread on the new switch hand-tight plus snug, and reconnect the 24V leads per your photo.
Test — Restore power, start the system, and confirm normal operation with no nuisance trip.
