Common Reasons for Overload Failure in Dometic Air Conditioners

Understanding why overload parts fail can help you avoid or troubleshoot potential issues. Here are some frequent causes:

Power Surges: RV and marine air conditioners are often exposed to fluctuating power levels. Sudden power surges, especially when connected to less regulated power sources, can lead to overload failure.
High-Temperature Conditions: Overload protectors are designed to handle heat, but extreme temperatures over prolonged periods can lead to wear and tear, eventually resulting in failure.
Improper Maintenance: Dust, dirt, and debris accumulation can affect the cooling capacity, causing the overload protector to overwork, which may eventually lead to burnout.
Frequent Cycling: Short cycling—when the AC frequently turns on and off—places excessive stress on the overload component, increasing the risk of failure.

Symptoms of a Failing Overload Part

If you notice these signs, it may be time to replace the overload part:

Frequent Tripping: The air conditioner repeatedly shuts down, often accompanied by a tripped breaker.
No Cooling or Reduced Cooling: The AC turns on, but there’s minimal or no cooling.
Electrical Smell or Odor: Overheating can produce a slight burning odor, indicating a malfunctioning component.
