Overview

This OEM high/low refrigerant pressure switch set protects the Tempstar TSH436GKA101 heat pump from running outside safe pressure limits. The high-pressure switch (part 1184656) opens the 24V control circuit if discharge pressure climbs dangerously high — from a blocked condenser, failed fan, or overcharge. The low-pressure switch (part 1184655) opens on loss of charge or restricted flow to prevent compressor damage. A failed or nuisance-tripping switch will lock out the unit and stop cooling/heating even when refrigerant pressures are normal.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter; switches mount on pressurized refrigerant lines.
Access — Remove the condenser service panel to reach the switch ports.
Document — Photograph the two control wires on each switch before disconnecting.
Remove — Most use Schrader-style ports allowing replacement without recovery; unscrew the switch and disconnect the leads.
Install — Thread the new switch onto its port and reconnect the leads per your photo.
Test — Restore power, call for operation, and confirm the unit runs without nuisance lockout.
