Refrigerator problem

I've been having problems with my fridge temp creeping toward 50 degrees at times. This morning, I slightly adjusted the temperature control knob (which is currently sitting at the recommended level - "3" on the 1 to 5 scale). Right now, it has been running ever since I got home from work and is down to 30 degrees!!

This Whirlpool top-freezer model is about five years old and has been giving us fluctuating temperature problems before. This past spring, I replaced the run capacitor and 'combination start device' (as partselect.com calls it), which seemed to have helped for the past few months.

What might the problem now be? Maybe the defrost timer or thermostat? By the way, as I'm typing this, I just heard the compressor finally shut off. The only other symptom I've noticed recently is, at times, when it sounds as if the compressor it ready to kick on, it hums for a second or two, but then kicks right back off.

Thanks in advance for any help you can provide!

That would be the fault of a problem start device. This fault would cause the temperatures to rise as the compressor not starting equals no cold.
Are you sure it's not the condensor fan humming ?

A model number here would be real helpful.

Luckily your unit has a mechanical thermostat and not an electronic control board. That thermostat is part # 2200859.

I cleaned off the coils a couple months ago when I replaced the run capacitor and start device. Last night, I put the thermometer in the freezer. After the compressor kicked off, it stood at 2 degrees. After a couple of hours or so of not kicking back on, it was at 20 degrees. Whenever I notice temps going up like this (or typically when the fridge is reading in the mid-40s), I turn the manual temperature knobs in the fridge. Sometimes, it kicks on when turning the the fridge knob; other times, when I turn the freezer knob. By chance, does this provide any evidence of what may be wrong or need replacement?

Thanks again!
Ryan

You should have only one thermostat. It's usually the one marked in numbers not letters and it would include an OFF position.

The other knob should just control a damper door between the fridge and freezer.

It sounds to me like the thermostat is bad.
