ZIS420NH
Monogram ZIS420NH 42-Inch Refrigerator Repair

Most common issues on this model
- Control versus real temperature
- Fan and airflow
- Gaskets on both doors
- Defrost and freezer frost
- Hinges on wide doors
The ZIS420NH is a Monogram 42 inch built-in side-by-side refrigerator, listed for 2014 through 2016. New units are no longer sold. At 42 inches it is wider than the 36 inch version, so the two doors are bigger and each gasket is longer.
When one side runs warm, we start with the gaskets and the hinges, since a long gasket has more places to leak. Then we test the evaporator fan, the defrost system and the sensor. Frost on the freezer wall usually points to moist air getting in or a defrost problem.
This model is retired, so we confirm the model and serial from the label and check which parts can be sourced. A written price comes ahead of the repair, which has a 30-day workmanship warranty.

What years does the brand list for the ZIS420NH?
The listing runs from 2014 to 2016, and the model is no longer sold new. We read the model and serial from your label and check parts availability before we quote the work.
Is the ZIS420NH a 42 inch model?
Yes, the brand lists it as a 42 inch built-in side-by-side refrigerator. At that width each door and gasket is larger than on a 36 inch model, which is why we check the seals first.
What if only the freezer side is warm?
We test the freezer fan and the defrost system first. The refrigerator side shares air with the freezer, so we check both sides, then the gaskets, and we confirm with a thermometer.
