Sub-Zero 7016004 Defrost Heater Assembly – SVCE

Sub-Zero

7016004-4323190

105.87

The Sub-Zero 7016004 Defrost Heater Assembly is a genuine OEM component responsible for removing frost accumulation from the evaporator during scheduled defrost cycles. Proper defrost operation is essential to maintain airflow, consistent temperatures, and efficient refrigeration performance.
A failed defrost heater can lead to heavy ice buildup, restricted airflow, warm refrigerator temperatures, excessive compressor runtime, and water leakage caused by improper ice melt. Replacing the heater assembly restores normal defrost operation and protects the refrigeration system from long-term damage.
This part is designed specifically for early-production Sub-Zero 590, 680, and 690 models and must be selected strictly according to serial number range.

Compatible With:
• Model 590
– Use regardless of serial number
• Model 680
– Use prior to Serial #1810000
– From Serial #1810000 to #2277174 → use 7016558
– Starting with Serial #2277174 → use 7022118
• Model 690
– Use prior to Serial #1810000
– From Serial #1810000 to #2269189 → use 7016558
– Starting with Serial #2269189 → use 7022118

⚠️ If you are uncertain about compatibility with your model, please provide your unit’s serial number for verification.

PARTS HELP

Frequently Asked Questions

Find clear answers about genuine OEM Sub-Zero, Wolf, and Cove replacement parts, compatibility verification, shipping, returns, and order support before you place an order.

Do you sell genuine OEM Sub-Zero, Wolf, and Cove replacement parts?

Yes. SubZeroParts.com focuses on genuine OEM replacement parts for Sub-Zero, Wolf, and Cove appliances. Our catalog includes parts for refrigerators, freezers, wine storage units, ice makers, ranges, ovens, cooktops, ventilation products, and other compatible appliance models.

How do I know if a part fits my appliance?

The best way to confirm fit is to check your appliance model number and serial number before ordering. Many Sub-Zero, Wolf, and Cove parts change by serial range, production version, or model variation. If you are not sure, use the Check Fit form and send us your model number, serial number, part number, and photos if available.

Why is the serial number important when ordering appliance parts?

A serial number can determine whether your appliance uses the current part number, an earlier version, or a different service replacement. Two appliances with the same model number may require different parts depending on the production range. Checking the serial number helps reduce incorrect orders, delays, and unnecessary returns.

Can you help me identify the correct part before I order?

Yes. If you are not 100% sure which part fits your appliance, send us your appliance details through the Check Fit form. Include the model number, serial number, part number if known, and clear photos of the part or rating plate. Our team will review the details and help you identify the correct compatible replacement part.

Do you ship Sub-Zero and Wolf parts across the United States?

Yes. We ship replacement parts to customers across the United States. Shipping options, delivery time, and availability may vary depending on the part, destination, carrier service, and current inventory status. Some large, fragile, or special-order items may require additional handling time.

What should I do if I already placed an order and need help?

If you already placed an order, use the Order Help form and include your order number, email address, and a short description of the issue. We can help with order status, tracking, shipping questions, returns, damaged items, wrong items, or compatibility questions related to your order.

Can I return a part if it does not fit?

Return eligibility depends on the item condition, product type, timing, and our return policy. Before ordering, we strongly recommend verifying compatibility by model and serial number. Electrical parts, installed parts, special-order items, or opened items may have restrictions. Please review the return policy before submitting a return request.

Are Sub-Zero and Wolf part numbers always the same as previous numbers?

Not always. Many OEM parts have current part numbers, previous numbers, replacement numbers, or service kit numbers. A previous number may be replaced by a newer part, but compatibility still depends on the appliance model and serial number. Product pages on SubZeroParts.com list current and previous numbers whenever available.
