Mitsubishi Electric u01a11308 Room Temperature Thermistor

Product Description

The Mitsubishi Electric u01a11308 is a room temperature thermistor designed to monitor ambient air temperature within a split or multi-split HVAC system. Thermistors of this type send real-time resistance-based temperature signals to the system control board, allowing the unit to regulate operation and maintain setpoint accuracy. This component is an OEM-grade replacement part suited for installation by licensed HVAC technicians performing diagnostic or preventive maintenance work on Mitsubishi Electric indoor air handling equipment.

This thermistor is typically found inside the indoor wall-mounted or cassette-style unit, positioned to sample room air temperature at the return air intake. When a room temperature thermistor fails, the system may display fault codes, fail to reach setpoint, or shut down entirely. Replacing it with the correct OEM part number restores accurate temperature sensing and proper system control behavior.

Key Features

• OEM replacement room temperature thermistor for Mitsubishi Electric indoor units
• Provides resistance-based temperature signal to the main control board

Compatibility

Designed as an OEM-style replacement room temperature thermistor for Mitsubishi Electric indoor HVAC units. Refer to the equipment service manual or Mitsubishi Electric parts documentation to confirm fitment for a specific model before ordering.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect all power to the indoor unit at the disconnect and confirm the absence of voltage before accessing internal components. Handle the thermistor lead wires carefully to avoid damage to the connector or wire insulation. Verify correct connector seating on the control board after installation before restoring power.
