Can the 33950S.S be used with a H4000-07 opener?
No, the H4000-07 model garage door opener uses the 20113R.S limit switch.
I just bought the upper limit switch and it has two wires coming out. does it matter which screw at the garage head the wires go into or or are they interchangeable Up Limit Switch (66", White) - 33950R.S
They can go to either one.
I'm looking for the down limit switch for an old Genie GX or GXL series opener. Is there a replacement part for that?
You can use the 20113R.S limit switch.
Do you have a limit switch for genie pro 88 model
We no longer have a limit switch for the Genie Pro 88.
