Coleman 1450-0221 Compressor Overload Protector for RV Rooftop A/C

The Coleman 1450-0221 is a compressor overload protector, also called a compressor overload or thermal overload. It is a thermal safety device that protects the compressor in Coleman Mach rooftop air conditioners.

Key Features:

• Thermal safety device that interrupts power when excessive heat or current is detected
• Helps prevent motor damage and extend system life
• Replacing a weak or failed overload restores proper compressor protection

Common causes of overload trips include low refrigerant charge, a dirty condenser coil, a failing fan motor, high ambient temperatures and compressor mechanical issues. If the unit trips repeatedly, check these causes as well as the overload itself.
