Description

This cavity temperature fuse (QFS-TA) is a safety thermal cutoff for electric ovens and ranges. It helps stop power to heating circuits when internal temperatures exceed safe levels, protecting the appliance and reducing fire risk. What it does:

• Acts as a one-time thermal cutoff inside the oven cavity to interrupt power if temperatures rise too high.
• Common symptom: oven or broil element does not heat even though controls and power appear normal.
• Common symptom: intermittent heating or a completely non-responsive heating circuit after an overheat event.
• Replaces a failed or tripped temperature fuse to restore proper over-temperature protection (does not reset; replace if open).

What's included: One cavity temperature fuse (QFS-TA). Install notes:

• Disconnect power to the appliance at the breaker before servicing.
• Locate the fuse in the oven cavity area or behind the back panel per your model's service instructions.
• Replace only with the exact fuse type; verify continuity before reassembly and restore power only after proper installation.
• If the new fuse opens again, do not repeatedly replace; investigate and repair underlying overheat or control faults.
