Mechanical Failure
Definition: When a home system or appliance stops working due to normal wear and tear, not external damage.
Examples of Mechanical Failure:
- HVAC compressor stops working
- Refrigerator motor burns out
- Washing machine pump fails
- Water heater element fails
- Garbage disposal motor dies
Why It Matters:
Home Warranty:
Homeowner's Insurance: Standard homeowner's insurance typically does NOT cover mechanical failures—only damage from covered perils (fire, theft, etc.).
What's NOT Mechanical Failure:
- Damage from power surges
- Storm or flood damage
- User error or misuse
- Lack of maintenance
- Pre-existing conditions
- Cosmetic issues
Documentation Importance:
- Describe symptoms clearly
- Note when problem started
- Mention any recent maintenance
- Don't speculate on cause—let technician diagnose
Maintenance Connection:
Age Factor: Older systems are more prone to mechanical failure. This is why home warranties can be valuable for homes with aging appliances and systems.
