This guide covers Jenn-Air Jenn 9 with practical, technician-backed advice.
V2 Vertical Dual-Fan Convection is one of the more distinctive engineering features in Jenn-Air’s wall ovens and range ovens, and understanding how it works explains why these ovens bake more evenly across multiple racks than a standard single-fan convection oven. Instead of one fan pushing air from the back wall, V2 uses two fans stacked vertically to solve a problem that has long affected multi-rack baking.

The Problem With Single-Fan Convection
A standard convection oven uses one fan, typically centered on the back wall, to circulate heated air around food. This works reasonably well for a single rack positioned at fan height, but performance drops off for racks positioned well above or below the fan, since airflow naturally weakens with distance from the source. Anyone who has baked multiple trays of cookies at once in a standard convection oven and noticed the top tray browning faster than the bottom has experienced this limitation directly.
How Two Vertically Stacked Fans Change the Airflow Pattern
V2 Vertical Dual-Fan Convection places two fans one above the other along the back wall, each covering a different vertical zone of the oven cavity. Rather than one fan trying to push air evenly across the entire height of the oven, each fan handles a smaller, more manageable zone, which produces a more consistent temperature and airflow across all the racks food is likely to occupy — top, middle, and bottom simultaneously.
Why This Matters for Multi-Rack Baking
The practical benefit shows up most clearly when you’re using more than one rack at once — a common scenario during holiday cooking or when batch-baking. With dual-fan circulation, a tray on the top rack and a tray on the bottom rack finish closer to the same time and with more even browning, reducing the need to rotate trays partway through baking. This also benefits larger single dishes, like a big roast or a multi-layer casserole, where consistent heat across the entire cavity height matters for even cooking.
How It Interacts With Oven Modes
V2 convection typically integrates with the oven’s various cooking modes — true convection bake, convection roast, and convection broil — applying the dual-fan airflow pattern across each mode rather than being a single standalone setting. This means the even-heat benefit carries through regardless of which convection mode you’re using for a given recipe, from bread proofing settings to high-heat roasting.
What Can Go Wrong With the System
Because V2 relies on two separate fan motors rather than one, a fault can affect just one fan while the other continues running — which can produce uneven baking that’s harder to diagnose than a complete convection failure, since the oven still appears to be working in convection mode. Unusual fan noise, a rattling sound during preheat, or baking results that have reverted to the uneven pattern typical of single-fan or non-convection ovens are all signs worth having checked.
How to Test Whether Your Oven Is Baking Evenly
A simple way to check dual-fan performance at home is baking a full sheet of cookies on two racks simultaneously, then comparing browning between the top and bottom trays without rotating them. Some minor variation is normal, but a dramatic difference in browning time between racks — well beyond what you’d expect from a properly functioning dual-fan system — is a useful, low-cost diagnostic clue to mention to a technician before a service visit.
Keep the System Running as Designed
If your V2 dual-fan oven isn’t producing the even results it’s designed for, a technician can diagnose which fan motor or related control circuitry is at fault without needing to replace the whole convection assembly. Check relevant error codes your oven displays, look up guidance for your specific model, or schedule a diagnostic visit if baking results have become inconsistent.
