Tempstar PTAC Thermostat for TEA07K25STC — OEM 1058517 Digital Control | Ships Today

Overview

This is the genuine OEM PTAC thermostat (control, part number 1058517 — "TSTAT PTAC X") for the Tempstar TEA07K25STC packaged terminal air conditioner. The thermostat is the brain of the PTAC unit: it reads room temperature, manages the heating and cooling call, and switches the compressor and fan accordingly. When it fails, the unit may stop responding to temperature changes, short-cycle, run continuously, or fail to switch between heat and cool modes. Installing the exact OEM control restores reliable, factory-spec operation without guesswork on wiring or compatibility.
