Would you keep repairing it or just replace it?

Original post

We have a situation where one of the units has an older refrigerator that's been giving us problems. We've already had someone come out to repair it once and now the tenant is reporting another issue with it.

The repair itself isn't crazy expensive but I'm starting to wonder if we're better off just replacing the thing instead of dealing with another service call a few months from now.

I'm curious how others would handle this. Do you usually try to get as much life out of appliances as possible or is there a point where you just call it and replace them? Especially interested in hearing from anyone managing multiple units where these costs can really add up.
