Sub-Zero Garbage Disposal Repair
Chicago and suburbs

Sub-Zero is known for built-in refrigeration designed for twenty-year service lives, and on the service side that means factory-level diagnostics and sealed-system certification required. Our technicians work on these machines every week and carry the parts that fail most often on them.

Disposals produce three calls: it hums but does not turn, it does nothing at all, or it leaks. Each one points somewhere different, and only one of the three usually means the unit needs replacing.

We use OEM Sub-Zero components wherever they are available, because on this brand aftermarket substitutes are a common cause of repeat failures. Every repair carries the same written 90-day warranty on parts and labour.

What actually fails

Jammed impeller. The most common call by far. A hard object wedges the grind ring. Clearing the obstruction and resetting the overload usually restores the unit completely, with no parts needed.

Tripped overload or failed switch. A dead disposal is often just a tripped reset button or a failed wall switch. This is why we check the simple things before quoting anything.

Sink flange seal. A leak at the top of the unit means the plumber's putty seal under the flange has failed. Resealing is a standard repair and saves the cabinet below.

Housing seal failure. Water from the bottom shell means the internal motor seal has failed. That unit cannot be repaired economically and we will recommend replacement instead.

Worn grind components. Rattling and poor grinding come from worn or broken impellers. On a good-quality unit these are replaceable; on a builder-grade one, replacement is cheaper.
