Walk-in door gasket replacement: how to know it is time

Gaskets are the cheapest repair in commercial refrigeration and often the most neglected. Here is how to audit them monthly.

Section 01

The dollar bill test

Close the door on a dollar bill. If you can pull it out with no resistance, the gasket has failed at that spot.

Section 02

Visible damage signs

Cracks, hardened rubber, torn corners, mildew stains. Any of these = replace.

Section 03

Cost vs. energy savings

A $180 gasket that saves 2 hours of compressor runtime per day pays itself back in under 90 days at Florida electric rates.

Section 04

Who should install

DIY is fine for magnetic gaskets. Dart-style gaskets on commercial units are worth a tech install.
