Overview

This OEM PTAC thermostat assembly (part 1058517) and matching control knob (part 1058437) replace the temperature-control unit on the Tempstar TEB09R00STA packaged terminal air conditioner. The thermostat senses room temperature and switches the 24V control circuit to cycle the compressor and fan, while the knob provides the operator-facing setpoint adjustment. Over time the thermostat contacts wear, the sensing element drifts, or the knob cracks and loses its detent — leaving the unit unable to hold temperature or stuck running in a single mode. Replacing both the thermostat and knob together restores accurate, repeatable temperature control for the room or suite.
