Hello, I recently moved to a new home with a sub zero 550 from 1994. When we moved in the thermostat was set to 10 with a large block of ice near the pull out tray. We defrosted and have had the unit at 38 degrees.
We recently had a power outage and it appears the unit struggles to get back down to temp. Typically the condenser fan and the fan inside the food section continuously runs. But after a power outage, it doesn't run all the time and the results is a warm fridge.
We've had a local company come out and top off refrigerant but the issue still persists after a power outage, often requiring 24 hours to get back to temp.
Any thoughts on potential repairs or if it's worth putting money into a 32 year old unit? The ice maker does not work and there is plenty of rust present as well.
Thanks in advance for all the help!
