Confirm the exact model suffix, serial range and component revision before ordering.

Symptoms and technician checks

Inspect this component when the equipment shows abnormal evaporator feeding after the refrigeration system has been diagnosed. Check refrigerant, capacity, fittings, equalization and sensing-bulb arrangement before attributing the fault to this part. These symptoms guide diagnosis; they do not establish that replacement is necessary.

Valve diagnosis requires checking system conditions and bulb installation. Match refrigerant and capacity; an incorrect valve can cause poor operation even if the fittings connect.

Before you order

Use manufacturer reference 3516224 and compare the item identification above with the removed part. Check the model and serial label, the corresponding parts diagram and any revision or serial break. Confirm the component supplied rather than assuming related brackets, wiring or accessories are included.
