We have a problem with a MCE Torqmax f4 drive and MCE says it needs to be replaced as they do not support the F4 and have moved on to the F5. Does anyone know if there is a company that will repair the older F4 drives?

No but please let me know if you find someone. I have done A LOT of F4 to F5 drive upgrades and while it can go smoothly, there have been several that have gone wrong when the old elevator won’t do an NTS stop in the down direction without tripping ETS due to light counterweights, loss of traction needing sheave/ropes replaced and I had one that would not do it without tripping on bus overvolt until I finally changed the braking resistors to the value KEB, not MCE suggested.

These guys do good work, have used them recently. They don’t take months and are cheaper then sending to keb or Mce.
