Dometic AC Overload Protector - Fits MRA Series Air Conditioners - Part# 290000108
The Dometic 290000108 AC Overload Protector is a critical safety component designed to protect your MRA series air conditioner from electrical overload and compressor damage. This thermal overload relay automatically disconnects power when the compressor draws excessive current due to overheating, locked rotor conditions, or electrical faults. Essential for maintaining the longevity of your RV air conditioning system and preventing costly compressor failures.
Key Features
- Automatic Reset Protection: Thermal overload relay that automatically resets once the compressor cools down, eliminating manual intervention
- Compressor Safeguard: Prevents catastrophic compressor failure by cutting power during overload conditions
- MRA Series Compatibility: Factory-specified overload protector designed specifically for Dometic MRA series air conditioners
- Direct OEM Replacement: Exact fit replacement for worn or failed overload protectors

Frequently Asked Questions
Q: How do I know if my overload protector has failed?
A: Common symptoms include the AC compressor not starting, the unit cycling on and off rapidly, or the compressor running but not cooling. If the overload protector is tripped, it may reset automatically after cooling, but repeated tripping indicates either a failed protector or an underlying compressor issue that needs diagnosis.
Q: Can I bypass the overload protector to get my AC working?
A: Never bypass the overload protector. This safety device prevents compressor damage and potential fire hazards. Running without overload protection can result in a burned-out compressor costing hundreds of dollars to replace. Always install a proper replacement overload protector.
Q: Is this a difficult part to replace?
A: Replacing an overload protector requires accessing the air conditioner's electrical components and working with live circuits. If you're comfortable with basic electrical work and have proper safety equipment, it's a straightforward replacement. However, many RV owners prefer having a qualified RV technician perform this repair to ensure proper installation and safety.
Q: Will this work on other Dometic air conditioner models besides MRA series?
A: This overload protector is specifically engineered for MRA series air conditioners. Using it on other models may result in improper protection or compatibility issues. Always verify your air conditioner model number and consult your unit's parts diagram to ensure correct fitment.
