Parts for AP075M: Room Air Conditioner Parts

This caster is the wheel assembly that lets your appliance roll and sit securely. Replacing a worn or damaged caster restores smooth movement and helps the appliance sit level for safer use. What it does:

• Replaces a failed wheel assembly so the appliance can be moved without scraping or sticking
• Supports appliance weight at one corner and helps maintain proper leveling
• Reduces rocking, uneven contact, and wheel-related noise when moving the unit
• Prevents damage to flooring and cabinet edges caused by a broken or missing caster

• Unplug the appliance and empty contents or secure heavy shelves before starting
• Support the appliance with a block or jack; do not rely on the caster or tilt it unsafely
• Remove the old caster fastener(s) and install the replacement using the same mounting method
• Check and adjust leveling after installation; replace additional casters if others are worn

This exhaust hose (also called a vent hose) routes hot discharge air from the unit to the window vent so the room can cool properly. Replacing a cracked or collapsed hose restores correct airflow and prevents hot air recirculation.

• Vents warm air from the appliance to the outside through the window kit
• Maintains proper airflow for normal operation
• Common signs of failure: visible cracks or tears, air leaks, hose won't stay attached, persistent kinks, reduced venting or poor cooling performance

• Unplug the unit and allow it to cool before service
• Transfer existing end adapters/couplers to the new hose as required and seat fully on both connections
• Route the hose as short and straight as possible; avoid sharp bends or crushing
• After installation, run the unit and check for secure connections and air leaks
