Do you have LA and DOT relays on the controller?

I don't remember if LA was in the controller off hand but DOT is. I initially encountered an issue with the (L) coil, which caused the elevator to bypass each floor without stopping. After replacing the (L) coil, it resolved that issue, then I discovered this problem. Both the front and rear doors experience this issue only during car call runs. This suggests that the problem is common to both doors and occurs before they enter their respective independent circuits, as the front and rear doors have separate circuits. Let me know what you think.

I would look into the L and DOT circuits.

As I stated earlier I replaced the L relay and verified everything appears fine. However, I noticed that if the L relay is held up for one second longer, it allows the doors to open. I'm unsure about the specifics of Westinghouse coils, but I know they have various types with different resistances. I also don't see any timing circuit for the L relay, but I'm wondering if the resistance in the coil might be causing it to drop out a bit prematurely. I've never seen that be an issue though.

I’ve never encountered this issue when swapping coils that had a little different in their resistance on other controllers, but I’m curious if anyone else has experienced something similar with Westinghouse coils and varying resistances. My parts department matched the part number, which the new number is different from the original. I can’t imagine a slightly different resistance being the problem, if that's even the case. See the attached print for the L coil circuit, all contact are fine, L just needs to hold 1 second longer. If anyone has a suggestion please let me know, if not I may have to add a delay off timer.

Thanks

I’ve had a coil with a solid core inside. It seemed to hold in for a bit longer than the normal relays. Notice the small L outside the L coil circle. I would inspect your old coil closely. I’m thinking it’s not the same as the original.

You may want to dig into the 70C and 80SC circuit , they are part of a non interference timing , possibly compare to the other car.

I think that is/was the issue, the old coil was a solid core and it's the same on the other car too. My parts department said the number I gave them was a cross reference match for the new one. Got to love these suppliers. As you know these coils suck to replace, not a lot of extra wire to play with and I also had to be on a step stool soldering wire extensions even though I'm 6' tall.

Yesterday I ended up adding a delay off timer circuit for about a half second. Worked perfectly and it took me only 15 minutes to install.

Thanks for responding.
