Overview
This genuine OEM PTAC thermostat kit fits the Tempstar TEB09R50DCA Packaged Terminal Air Conditioner. It includes the thermostat control (OEM part 1058517), the matching control knob (OEM part 1058437), and the low-temperature thermostat/cutout (OEM part 1059022). The main thermostat senses room temperature and cycles the compressor, fan, and heat to hold the setpoint, while the low-temp control protects the system from freeze conditions. Failure symptoms include a room that never reaches setpoint, short cycling, no response from the controls, a freely spinning knob, or nuisance low-temperature shutdowns. OEM replacement parts restore accurate control and built-in protection.
