Diagnosis
Wobbly or stuck wheels on your De'Longhi TRD40615E are typically caused by debris wound tightly around the wheel axles (like pet hair, carpet fibers, or thread) or by physical damage, such as cracked plastic wheel housings or a broken axle from the heater being dragged or tipped over.
How to Fix It
- Unplug the heater and let it cool completely.
- Carefully tilt the unit backward, supporting it by the main housing—do not lay it on its side or front, as oil may leak.
- Inspect each wheel. Manually spin them to find which are stuck or wobbly.
- For stuck wheels, use needle-nose pliers or a small pick to gently pull any wound debris from the metal axle shaft between the wheel and the plastic housing.
- Wipe wheels and axles clean with a damp cloth, then dry thoroughly.
If That Didn't Work
If the wheel itself is cracked or the axle is bent, the entire wheel assembly likely needs replacement. These are not generic caster wheels. You must contact De'Longhi Customer Service directly with your model number (TRD40615E) to order the correct factory replacement wheel kit. They can provide the specific part number and any special installation instructions.
Heads Up
Always move the heater by pushing the sturdy handle on the front. Never drag it by the power cord or the thermostat knob, as this strains the internal wiring and can damage the wheel mounts.
