You should not have a double pole in that switch circuit. There could have been a loose connection, one of the switches failed, or both. But if you replaced the 4-way with a double pole it explains exactly how they currently function. A double pole is basically two single pole switches with one toggle that switches both on or off. A 3-way is a single pole double throw; it always connects a common terminal to one of the two remaining terminals, that in this application we call "travelers". Those have to be connected to another 3-way. If you install both 3-ways in the same orientation, if both are up or both are down, the light will be on. if they're different, the light is off. You can cut those two "travelers" anywhere between the two 3-way's and install a 4-way. The four terminals make contact for both travelers either straight thru or diagonally; basically just swapping the connections on the other 3-way. You can install as many 4-way's as you like between the 3-way's because one of the two travelers will always be hot. A double pole will only create an open or closed connection for the travelers, which is why it will never work.

If so that is a double pole switch and not the one you want. A 4 way does not have on and off written on it. Start there. RE: 3 way switch - Bob10 - 12-01-2021 I have only had to wire up a 4 way switch from scratch once. It was before the internet and youtube I started to think candles would be a good option RE: 3 way switch - Jack01 - 12-04-2021 (11-29-2021, 03:26 PM)Jack01 Wrote: Please help Thank you very much for all the info.
