The Tecumseh K90-19 Thermal Overload Protector is a vital component used in HVAC systems to prevent compressor motors from overheating. This protector, which is specifically made to work with Tecumseh compressors, works by continuously checking the motor windings' temperature. The thermal overload protection immediately cuts off the motor's electrical power if it senses that the temperature has risen above acceptable limits, protecting the component and perhaps averting system failure. The K90-19 Thermal Overload Protector, whether installed in air conditioning units, refrigeration systems, or heat pumps, guarantees dependable and secure compressor performance. Its accurate operation and sturdy design increase system longevity and performance while lowering maintenance needs and lowering the risk of motor burnout. This protector enhances the overall performance, energy efficiency, and dependability of HVAC systems by offering efficient thermal protection, guaranteeing constant comfort for occupants.

Product Number: K90-19
OEM Part Number: K90-19
Product Description:  A thermal overload kit is designed to protect the compressor motor against overheating conditions. It operates based on temperature rather than electrical current. The primary function of the thermal overload kit is to monitor the temperature of the compressor motor. It is equipped with a thermal sensor that detects excessive heat generated during operation. When the compressor motor reaches a critical temperature due to prolonged operation or abnormal conditions, the thermal overload kit intervenes by interrupting power to the motor. The thermal overload kits incorporate a reset mechanism that allows the protection to be reset manually after it has tripped due to overheating. Thermal Overload Protector K90-19 Compressor includes diagnostic indicators or alarms that signal when the thermal protection has been triggered, helping technicians quickly identify the issue. Thermal overload kits are rated for specific temperature thresholds, ensuring that they respond appropriately to various HVAC system operating conditions. Thermal overload kits are built with reliable and durable components, ensuring they can withstand the demanding conditions within HVAC systems. Thermal overload kits are rated for specific temperature thresholds, ensuring the response is appropriate to various HVAC system operating conditions. Installing a thermal overload kit can be cost-effective, as it helps prevent costly compressor motor replacements due to overheating damage. Thermal Overload Protector K90-19 Compressor offers temperature control features that allow for adjustments to the trip temperature, allowing customization based on a specific system. A thermal overload kit used in HVAC systems offers crucial protection against motor overheating. It does so by monitoring temperature rather than electrical current, complementing the electrical overload protection offered by other types of overload kits. 

Key Features offered by the thermal overload kit are:

  • Monitors compressor motor temperature.
  • Durable components for dependable operation.
  • Prevents motor damage due to overheating.
  • Rated for specific temperature thresholds.
  • Allows trip temperature adjustment.

Customer Questions
Is it possible to adjust the temperature threshold at which the thermal overload kit triggers?

Some kits offer adjustable temperature settings, while others have fixed thresholds. Check the kit's documentation to determine if it's adjustable.

Can I use a thermal overload kit as the sole protective device for my HVAC compressor, or should I use it in conjunction with other protection mechanisms?

While a thermal overload kit offers critical protection against overheating, it's advisable to use it in conjunction with other protective devices like electrical overload kits for comprehensive protection.

Is it possible to retrofit an existing HVAC system with a thermal overload kit, or does it need to be installed during the initial setup?

Retrofitting with a thermal overload kit is possible, but compatibility and ease of installation may vary. Consult an HVAC professional for guidance.

What maintenance is required for the Tecumseh K90-19 Thermal Overload Protector?

Inspect the protector regularly for signs of overheating, corrosion, or physical damage. Ensure connections are clean and secure. Test operation periodically, and replace immediately if it trips incorrectly or shows damage to maintain safe motor protection.

What are common issues with the Tecumseh K90-19 Thermal Overload Protector?

  • Frequent or false tripping.
  • Failure to reset after overload.
  • Loose or corroded electrical connections.
  • Inconsistent protection of the motor.

Installation Steps

Step1: Turn off power to the system.

Step2: Locate the existing thermal overload protector on the motor.

Step3: Carefully disconnect the wires from the old protector.

Step4: Remove the old protector from its mounting position.

Step5: Install the new overload protector securely in place.
