Mitsubishi Electric U41001200 Thermistor

Maintain precise environmental control with the Mitsubishi Electric U41001200 Thermistor, a critical OEM component designed for high-performance HVAC system diagnostics and thermal regulation. This temperature-sensitive resistor provides real-time data to the indoor controller board, ensuring optimal refrigerant flow and preventing system errors like the common two-time flash code. Engineered specifically for Mitsubishi mini split repair, the U41001200 functions as the Th22/23 or TH5 sensor in various air handler configurations. Its accurate resistance-to-temperature curve is vital for preventing coil icing and maintaining consistent compressor modulation. Using a genuine Mitsubishi Electric replacement part ensures full compatibility with the internal logic of the system, protecting the high-efficiency ratings of your ductless heating and cooling equipment. Whether you are performing routine maintenance or troubleshooting a logic failure, this HVAC temperature sensor is the technician's choice for restoring factory-standard performance in residential and commercial applications.

• Direct OEM Compatibility: Verified for use in PEAD-A and PEFY-P series indoor units, ensuring seamless integration with existing wire harnesses.
• Accurate Thermal Sensing: High-precision thermistor technology prevents erratic system cycling and improves energy efficiency.
• Rugged Build Quality: Built to withstand the moisture and temperature fluctuations common in evaporator coil environments.
• Optimized System Protection: Relays critical TH5 and TH22/23 data to prevent overheating or freezing of the heat exchanger.

• How can I tell if my U41001200 thermistor is faulty? Technicians should perform a resistance test using a multimeter; compare the kOhm readings against the specific resistance chart in the unit's service manual at known temperatures.
• Which Mitsubishi models use this specific sensor? This part is widely used in PEAD-A09AA7 through PEAD-A42AA7 models and PEFY-P series medium static ceiling-concealed indoor units.
• What does a two-time flash on the indoor unit indicate? On many Mitsubishi systems, this diagnostic code points directly to a fault within the thermistor circuit, often requiring a replacement of the U41001200.
