## Description

Robinair's 16916 original equipment oxygen sensors are the same oxygen sensors your Robinair R-1234yf AC Machine or Refrigerant Identifier was built with when new, offering unmatched performance and ease of installation. Robinair AC Machines and Refrigerant Identifiers that incorporate oxygen sensors provide two levels of notification. The first notification displayed by the machine lets you know that the sensor is nearing the end of it's life and should be replaced as soon as possible. If the sensor isn't replaced in a timely fashion and the sensor reaches the end of its useful life, the second notification tells the operator that the oxygen sensor has failed and that the unit will not recover or allow tank fill until the sensor is replaced. Easy to follow instructions are included in the maintenance section of the owners manuals included with Robinair R-1234yf AC Machines and Refrigerant Identifiers. Once replaced, the AC Machine or Refrigerant Identifier immediately returns to full functionality. Authentic Robinair 16916 Oxygen Sensors are exact replacements for Robinair AC1234-4, AC1234-4SL, AC1234-4 230, AC1234-6, and AC1234-9 AC Machines as well as Robinair 16990 and 16995 Refrigerant Identifiers. Beware of aftermarket replacements that may not possess the same specifications and/or operating parameters - only genuine Robinair 16916 oxygen sensors can deliver exact OE fit and performance.

One of my A/C machines broke down at an auto shop that I own. This O2 sensor to repair the machine was over a thousand dollars from the dealer. I was able to get it for half the price on Amazon. The machine works perfectly again.
