Replacement oxygen sensor for Robinair R-1234yf machines and refrigerant identifiers. Your 1234yf machine or identifier should provide advance notice when the oxygen sensor is nearing the end of its lifespan. Oxygen sensor replacement is required to return machine to normal operation. If the oxygen sensor expires, neither the integrated identifier, nor the machine, is able to recover or add refrigerant to the internal tank.
No structured vehicle fitment data is available. Compare the listing with the vehicle and existing part before ordering.

Our Robinair 1234-4 machine suddenly stopped working with the message the O2 sensor failed. Needed one ASAP and the Robinair store in Amazon delivered. This sensor is the same as the original and it is easy to replace.
