### ⭐⭐⭐⭐⭐ OEM LIMIT SWITCH
*by J***N on January 28, 2024*

Exactly what I needed, to fix our heater and keep the house warm!!!

### ⭐⭐⭐⭐ Great OEM product, with new look for 2020
*by A***8 on January 14, 2020*

My York Diamond 80 furnace was flashing red 8 times and blowing cold air. The 8 red flashes are an error code that means the furnace tried to light up 5 times and failed, and is currently in lockout mode. Lockout mode means the furnace will only blow cold air until it is reset. I added a photo showing the location of three York parts typically associated with this error code including this limit switch. I purchased this L140-30 (i.e., open 140*F- close 110*F) limit switch and it fixed my problem. I also changed my air filter. I don’t know why so many people are giving it 1 star for the new look. The specs and dimensions are both correct and it works. The description states it is an OEM product by Replm for York. The original part that came with the furnace was by Texas Instruments for York. Texas Instruments no longer makes this part for York… that was 20 years ago. If you want the original part, go back to 1999. I think it’s more than reasonable to expect parts to change over the course of 20 years. It’s not like anyone is looking inside your furnace to notice the change in appearance. I did have to write the original York part number on the replacement switch, so that the next time this thing goes out I will know what to buy. I docked a star because the product didn’t include the original York part number on it. While it may be easy to find an L140-30 limit switch, I believe the dimensions and mounting holes are not the same across different furnace manufacturers. So basically, knowing the York part number is important so you can find a switch with the correct physical dimensions.
