this sensor is cross-compatible with various models within the Carrier family of products that specify the 48GS400192 part number

the "U" designation typically refers to universal retail packaging

though you should always verify the specific amperage draw of the compressor against the 9

it provides superior thermal conductivity and corrosion resistance

or physical damage during descale procedures

Resideo Q340A1066 Thermocouple this sensor is cross-compatible withThe Resideo Q340A1066 is a professional grade Universal 30mV Thermocouple designed for high reliability pilot flame sensing in standing pilot gas fired heating systems. This 18 inch thermocouple features a heavy duty construction with a focus on Maximum Copel content to ensure long term durability and consistent millivolt generation. When the pilot flame contacts the tip, the resulting temperature differential produces a stable 26mV 32mV open circuit
