Mitsubishi Electric E22D68307 Thermistor
The Mitsubishi Electric E22D68307 is a critical indoor coil thermistor designed for precision temperature sensing in split-system air conditioners. As a genuine OEM replacement part, it ensures the control board receives accurate resistance feedback from the evaporator coil to manage compressor modulation and prevent coil icing. This NTC thermistor (Negative Temperature Coefficient) features a 25-inch lead length with a 1-inch sensor bulb encased in ceramic for superior thermal response and resistance to environmental fluctuations.
Engineered for technical reliability, the Mitsubishi E22D68307 indoor thermistor operates within a standard voltage range of 12-24V DC. It is specifically calibrated to match the resistance-temperature curves of the MSZ and MSY-GE series, ensuring the system maintains optimal HVAC efficiency. When troubleshooting common errors like a two-time flashing light on the indoor unit, this part is the primary fix for mini split thermistor failure. Its high sensitivity allows for real-time monitoring of the refrigerant circuit, protecting equipment from thermal shock and ensuring consistent discharge temperatures.
Key Benefits for Technicians
- Exact OEM Calibration: Eliminates guesswork by matching the manufacturer's specific resistance-to-temperature charts for a Mitsubishi AC sensor.
- Broad Compatibility: Drop-in fit for MSZ-GE06NA, MSZ-GE09NA, MSZ-GE12NA, MSZ-GE15NA, MSZ-GE18NA, and corresponding MSY-GE models.
- Durable Construction: High-quality ceramic material and reinforced leads withstand frequent thermal cycling between 40°F and 302°F.
- System Protection: Critical for accurate defrost cycles and preventing the indoor coil from freezing during low-load operation.
Common Questions
How do I test if this thermistor is faulty?
Disconnect the part from the PCB and use a multimeter in kΩ mode. At 77°F (25°C), the resistance should typically measure around 10kΩ. If you see an "open" or "short" reading, or if the resistance does not fluctuate when heat is applied, a replacement is necessary.
Can I use a generic 10k thermistor instead of the E22D68307?
While some generic sensors have the same base resistance, Mitsubishi units require a specific B-value curve for the logic board to calculate temperature correctly. Using non-OEM parts can lead to inefficient operation or persistent error codes.
Does this include the spring clip?
This part includes the sensor and lead wire assembly. The existing metal spring clip on the indoor unit's copper tubing is typically reused to secure the new sensor bulb firmly against the coil.
