Roller ring for microwave oven 12170000004331 (T03)

Roller Ring (Turntable Support) for Panasonic Microwave Ovens

We offer an original roller ring support, an essential component of the turntable rotation system. Installed at the bottom of the microwave cavity, it serves as a mobile foundation for the glass tray, preventing it from tilting and rubbing against the bottom.

Technical Specifications:

• Application: designed for compact microwave ovens with a 255 mm turntable diameter.

• Number of Rollers: 3 maneuverable wheels.

• Material: special heat-resistant, food-grade plastic, durable against long-term microwave radiation and temperature fluctuations.

• Key Feature: lightweight yet robust construction that ensures minimal noise levels during operation.

Model Compatibility:

This roller ring is specifically developed for popular compact Panasonic series:

• NN-ST25HB (Black series)

• NN-ST27HM (Silver series)

• And other 20-liter Panasonic models utilizing the same chassis.

When Should You Replace the Roller Ring?

• Unusual Noise: if you hear rattling, grinding, or atypical friction sounds underneath the tray during operation.

• Uneven Rotation: the tray "limps," tilts, or scrapes against the cavity walls.

• Roller Wear: the wheels are jammed, worn down, or show signs of melting due to grease build-up.

• Mechanical Damage: a crack in the plastic ring itself, causing it to lose its geometric shape.

Why Choose an Original Spare Part?

• Precise Height: the rollers feature a specific height calibrated exactly for the coupler used in the ST25/ST27 models. An incorrect height will cause the tray to slip out of its grooves.

• Arcing Resistance: the material of the original ring is non-conductive and will not char if an accidental electrical arc (sparking) occurs.

• Extended Lifespan: original rollers are crafted from a wear-resistant polymer that won't flatten or degrade even after thousands of rotation cycles.

Technician's Tip:

If you notice black spots or burn marks on the ring, replace it immediately. Carbon build-up on plastic becomes electrically conductive, which can cause severe damage to the enamel on the bottom of your microwave. Keep the rollers clean by washing them regularly with simple soapy water.

Ensure your microwave operates quietly and reliably with original Panasonic components!
