Mitsubishi Electric r01h99202 Ambient Thermistor Suction Pipe

Product Description

The MITSUBISHI ELECTRIC r01h99202 is a replacement ambient thermistor suction pipe designed for use in Mitsubishi Electric HVAC systems. This component monitors suction-line temperature and feeds that signal to the system control board, enabling accurate refrigerant circuit management. The unit ships as a single assembly with a total lead length of 48 inches and a probe length of 0.875 inches. Licensed HVAC technicians working on Mitsubishi Electric mini-split and multi-zone systems will typically handle this replacement during a controls or sensor diagnostic service call.

This thermistor is intended for residential and light-commercial Mitsubishi Electric split-system and multi-split applications where suction-pipe temperature sensing is required. It is a direct replacement part supplied as a single unit. Installation typically occurs when a system fault code indicates a suction thermistor error or when sensor resistance readings fall outside the manufacturer's specified range during service diagnostics.

Key Features

• 48-inch lead length provides routing flexibility within the unit cabinet
• 0.875-inch probe length sized for standard suction-pipe contact mounting
• OEM-specification replacement for Mitsubishi Electric systems
• Single-assembly kit — one thermistor suction pipe per package

Compatibility

Designed as an OEM-style replacement thermistor suction pipe for Mitsubishi Electric split-system and multi-split HVAC equipment requiring suction-line temperature sensing. No specific superseded part numbers are associated with this component.

Installation Notes

Installation of this thermistor should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the indoor and outdoor units before removing the existing sensor or routing new leads. Secure the probe firmly against the suction pipe and fasten leads away from moving parts or sharp edges to prevent chafing. Follow applicable local codes and the equipment service manual for sensor mounting and connector termination procedures.
