How to Replace the Turntable Parts on a Panasonic NN-SU696S Microwave — Step-by-Step Instructions
Step-by-step instructions for the Panasonic NN-SU696S (countertop microwave, 1.3 cu ft). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
Everything here happens inside the cooking cavity with the microwave unplugged. Never remove the outer metal cabinet of a microwave. The high-voltage capacitor inside stores a charge that can kill you, and it holds that charge after the unit is unplugged. Every step in this guide stays outside the cabinet or inside the cooking cavity — if a repair needs the case off, it is a job for a technician. If the fault turns out to be the turntable motor beneath the cavity floor, that is a cabinet job — hand it over.
Tools
- Warm soapy water
- Soft cloth
- Phone camera
Parts
- Roller guide / support ring $8–$25
- Turntable coupler or drive hub $8–$20
- Glass turntable plate $20–$45 if cracked
Step by step
-
1 Unplug the microwave
Even for cavity work, get it off the power.
-
2 Lift out the glass plate and roller ring
Both should come straight out. Photograph how the ring sits before you remove it.
-
3 Clean the recess underneath
Food and grease build up in the well under the plate until the ring cannot roll. A surprising number of dead turntables are just dirty — clean it thoroughly with warm soapy water and dry it.
-
4 Inspect the roller ring
Check every wheel turns freely and none are missing, cracked or flat-spotted. A worn ring is a few dollars and is the single most common cause of this fault.
-
5 Check the coupler
In the middle of the cavity floor is a small plastic coupler with splines that the glass plate sits on. Look for rounded or stripped splines — if the plate wobbles or slips on it, that is your part.
-
6 Test the drive with the plate out
Refit the coupler only, plug the unit in, and run it for a few seconds with a cup of water inside. If the coupler turns, your problem was the ring or the plate. If it does not turn at all, the motor beneath has failed.
🔧 Hand-off point: A dead turntable motor is where this job stops being a DIY one — it lives under the cavity floor behind the cabinet, alongside the high-voltage capacitor. Hand it over at this point. find a microwave repair pro near you → -
7 Reassemble
Ring first, then the plate seated squarely on the coupler. It should rotate smoothly by hand with no grinding.
Panasonic NN-SU696S notes & error codes
Panasonic’s H-series codes are self-diagnosis results specific to their designs and generally point at the high-voltage section. On a countertop unit, an H-code is usually where the repair conversation ends — worth knowing before paying a diagnostic fee.
| Code | What it means |
|---|---|
| F## codes | Numbered control fault codes shown on the display |
| H## codes | Panasonic self-diagnosis codes; the H9x series relates to the high-voltage or inverter section |
Full details for this machine — common problems, causes, and costs — are in the Panasonic NN-SU696S repair guide. The general version of these instructions is here.
If the coupler does not turn under power, the turntable motor has failed. Reaching it means opening the cabinet on almost every model, which puts it firmly in professional territory. On a countertop microwave, replacing the appliance is usually the better financial call. If you'd rather skip it entirely, find a microwave repair pro near you →
