What this usually means
A new noise from an oven is usually a fan bearing, something touching a fan blade, or panels expanding as the cavity heats. The last of those is normal and the first two are not. The hardware on this kind of appliance rarely surprises anyone; the supervision around it is where the ambiguity lives. Work through the modes and the conditions first, because both are free and both narrow the field sharply.
The observable signs
- Ticking and pinging as the oven heats and cools — Metal expanding against metal, which is normal on every oven.
- A rattle from the back of the appliance — A loose panel, a shelf or something resting against the casing.
- A scraping noise that changes with fan speed — Something contacting a fan blade, often a shelf or a foil sheet.
- NEAR MISS: a hum from a gas oven with no fan running — That is usually a valve or a regulator and is a different page.
Most likely first
- Convection fan bearing wear — Most likely here. It leads on an oven of this class because the convection fan runs in the cavity at cooking temperature throughout every use. A fan inside the cavity that works at high temperature for years. It announces its wear as a rising whine before it fails.
- Cooling fan bearing wear — Next most likely. The more important of the two, because a cooling fan that stops leaves the control electronics unprotected.
- Something contacting a fan blade — Third in the order. A shelf pushed too far back, a foil sheet or a dish lid. Free to correct and immediately obvious once found.
- Normal thermal expansion — Then this one. Ticking and pinging as panels grow and shrink.
- Body: These are ordered for this brand and appliance rather than for the appliance class in general, and the ordering is qualitative.
What to check first, and why that first
- Note whether the noise tracks a fan or the heating — Fan noise starts and stops with the fan; expansion noise follows temperature.
- Check whether the noise continues after cooking has ended — Noise after switch-off is the cooling fan, which runs on.
- Remove the shelves and anything at the back of the cavity — Contact with a fan blade is the easiest cause to eliminate.
- Body: The order below separates noises that track a fan from noises that track temperature, which is the distinction that matters.
What an owner can safely check
- Let the oven cool completely, then remove all shelves and trays — Contact noise usually disappears at this step.
- Listen after switch-off to identify the cooling fan — It runs on after cooking, which distinguishes it from the convection fan.
- Check the appliance is sitting squarely in its housing — A built-in appliance touching its cabinet transmits every vibration.
- STOP before removing a rear panel or a fan assembly — Those are live, high-current assemblies behind covers.

Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never reach into a cavity to investigate a fan noise while the oven is hot or powered, and do not continue to use an oven whose cooling fan has become noisy or stopped, because the electronics above the cavity depend on it.
The point at which to call someone
Call when the noise tracks a fan rather than temperature, and call promptly when it is the cooling fan: a failing cooling fan damages the control assembly it protects, and that is a far more expensive repair than the fan itself. Note whether the fault appears from cold or only once the appliance is hot.

Scope of this page
This page is written for the appliance class rather than for one Brigade family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
