Ranco A22-2453 Control

The Ranco A22-2453 Control is a heavy-duty cycling temperature control engineered for high-performance in room air conditioning and light commercial refrigeration environments. Featuring a Single Pole Double Throw (SPDT) switch configuration, this adaptable unit allows for versatile wiring options, including close-on-rise action for cooling compressor protection. The 39-inch copper capillary utilizes a cross-ambient sensing element with a 3/8" x 4" bulb, ensuring accurate temperature response regardless of the ambient conditions surrounding the control body. With an adjustable temperature range of 59°F to 90°F and a constant differential of 6°F, it provides stable thermostatic cycles for equipment like the GE WJ28X505 and other OEM HVACR units. This universal kit is designed for immediate field replacement and includes a break-off shaft, dial knob, and mounting bracket to streamline installation on the job site.

Key Benefits for Technicians:

• Broad Compatibility: Functions as a direct or adaptable replacement for various OEM controls in room air conditioners and beverage coolers.
• Precision Sensing: The cross-ambient fill prevents control hunting by ensuring the bulb, not the bellows, dictates the switching action.
• Durable Contacts: Rated for up to 20A at 120V/240V, handling high-amperage compressor loads without premature pitting.
• Complete Installation Kit: Ships with all necessary hardware, reducing the need for additional trips to the parts house.

Common Questions:

Does this control work for both heating and cooling?
Yes. Because it utilizes an SPDT switch, you can wire it to either open or close the circuit on temperature rise, making it suitable for multiple HVACR applications.

Can the differential be adjusted in the field?
No. The Ranco A22-2453 features a fixed 6°F differential. While there is a calibration screw in the insulator block, it is factory-set and should not be adjusted, as it can compromise the accuracy of the 59-90°F range.

How do I handle the break-off shaft?
The included shaft is notched to allow you to snap it to the specific length required for your unit's dial depth, ensuring a professional flush-mount finish.
