Overview

This genuine OEM PTAC thermostat kit is the direct replacement for the Tempstar TEB09R50SPA Packaged Terminal Air Conditioner. It includes the thermostat control (OEM part 1058517) and the matching control knob (OEM part 1058437). The thermostat senses room temperature and switches the compressor, fan, and heat to maintain the dial setpoint. When it fails, you'll typically see temperatures that never reach the setting, short cycling, a unit that won't turn on or off, or a knob that spins without adjusting the temperature. An OEM replacement restores accurate, reliable temperature control.
