7801B378 MITSUBISHI Hvac Evaporator Temperature Switch

Review MITSUBISHI Genuine Hvac Evaporator Temperature Switch

The Mitsubishi 7801B378 HVAC Evaporator Temperature Switch is an essential component in ensuring optimal performance and energy efficiency for your Mitsubishi air conditioning system. This temperature switch is designed specifically for use in evaporator units, and it plays a crucial role in regulating the temperature of the air being distributed throughout your home or business.

This temperature switch features a bimetallic construction, which allows it to respond quickly and accurately to changes in temperature. The bimetallic element is made up of two metals that are bonded together and shaped into a coiled spring. When the temperature of the refrigerant passing through the switch reaches a certain point, the bimetallic element bends, making contact with the switch terminals and completing an electrical circuit. This action then triggers the compressor or fan to turn on or off, depending on the temperature setting of your thermostat.

The 7801B378 temperature switch is designed with a high-temperature rating of 115 F (46 C), making it suitable for use in warm environments where the temperature of the refrigerant may be high. It is also constructed with a corrosion-resistant coating to protect against the damaging effects of moisture and other contaminants that may be present in the air conditioning system.

This temperature switch is a direct replacement for the original equipment manufacturer (OEM) part, ensuring a perfect fit and reliable operation. It is easy to install, with clear and concise instructions included in the packaging. The switch terminals are color-coded for easy identification and connection to your wiring harness.

In summary, the Mitsubishi 7801B378 HVAC Evaporator Temperature Switch is an essential component for maintaining the temperature and energy efficiency of your Mitsubishi air conditioning system. Its bimetallic construction allows for quick and accurate temperature sensing, while its high-temperature rating and corrosion-resistant coating ensure long-lasting performance in demanding environments. This temperature switch is a direct replacement for the OEM part and is easy to install for DIY enthusiasts or professional technicians.
