Mitsubishi Electric u01a09307 Indoor Coil Thermistor

Product Description

The Mitsubishi Electric u01a09307 is an indoor coil thermistor designed for use in split-system and multi-zone mini-split air conditioning equipment. This sensor monitors refrigerant coil temperature and feeds real-time data to the system control board, allowing the unit to regulate cooling and heating cycles, prevent freeze-up, and protect the system from operating outside safe temperature limits. It is a direct OEM component intended for installation by licensed HVAC technicians during routine service or component-level repair.

This thermistor is suited for residential and light-commercial indoor air handler units where coil temperature sensing is required for proper system operation. It mounts at or near the evaporator coil and connects to the main control circuit. Technicians typically encounter this component during troubleshooting of fault codes related to coil temperature errors or during preventive maintenance inspection of sensor integrity.

Key Features

• OEM coil thermistor for accurate temperature sensing at the indoor evaporator
• Provides coil temperature feedback to the control board for cycle regulation and freeze protection
• Direct OEM replacement to maintain factory system performance and diagnostics
• Compact sensor form factor for installation in tight air handler enclosures

Compatibility

Designed as an OEM-style replacement indoor coil thermistor for Mitsubishi Electric split-system and multi-zone mini-split indoor units requiring part number u01a09307.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect all power to the indoor unit at the breaker before removing or installing any sensor components. Ensure the thermistor connector is fully seated and free of corrosion before reassembling the unit. Verify correct operation by checking for active fault codes after restoring power and running the system through a test cycle.
