Review on 👍 Honeywell L4064B2210: Reliable Furnace Limit Control for Efficient Heating by Adam Nelson

I used this to replace a very old Honeywell L4064A3046. The model number has been deleted so it may be the wrong model number, the shaft length was 11.5 inches. If you were to buy a new OEM L4064A3046 today, it would only be 11 inches. I really don't know why that is. But this L4064B2210 is an almost exact replacement for mine, except my old one didn't have a manual fan button. So my advice to any buyer is to take an old one and measure the rod and not just go by the model number. I was told that the L4064B2210 is not a replacement for my model because it was 0.5" longer, but it definitely is and certainly has the same shaft length as my original. Photos prove it.
