Product Overview

OEM Part Details OEM Part Number: PD-120-906 MPN: PD-120-906 SKU: PD-120-906 Part Type: Single Stage Temperature Control OEM Status: VERIFIED Product Overview The PD-120-906 single stage temperature control is a refrigeration control component used in commercial refrigeration equipment. Its role is to respond to the equipment temperature-sensing arrangement and participate in the control circuit that manages temperature response. When a temperature control is not responding consistently, commercial equipment may require careful diagnosis to determine whether the control, sensing element, terminals, wiring, or another related component needs attention. Temperature controls are important because they help the refrigeration system respond to changing cabinet conditions through the proper control sequence. This part should be selected by its verified OEM number, PD-120-906, rather than by appearance alone. Similar controls can have different terminal arrangements, sensing-element configurations, mounting details, or operating characteristics that are not visible in a product image. For commercial equipment service, compare the removed component with the available product information and review the equipment data plate before ordering. Careful identification helps reduce wrong-part orders and gives a qualified technician a dependable reference point during diagnosis and replacement planning.

Product Function

Product Function This single stage temperature control supports the temperature-control function in commercial refrigeration equipment. It works with the equipment sensing arrangement and control circuit to respond when temperature conditions call for a change in the refrigeration control sequence. The control is an electrical component, so its terminals, mounting position, and sensing-element routing should be compared with the original component before replacement. A temperature concern does not confirm that this control is the cause; related wiring, relays, contactors, sensing components, and the broader refrigeration system should also be evaluated by qualified service personnel.

How This Part Works

How This Part Works A single stage temperature control uses a sensing element to detect temperature conditions and communicates through its control contacts as part of the equipment control circuit. Depending on the condition sensed, the control can change the circuit state so related refrigeration controls can respond. Its operation depends on the correct relationship between the control, the sensing element, the connected terminals, and the equipment wiring. The sensing element may be routed as a bulb, capillary, or probe arrangement depending on the equipment design. That routing, along with terminal layout and mounting details, is important when comparing a replacement. Damage to terminals, a disturbed sensing element, wiring concerns, or a separate control-circuit issue can produce similar equipment behavior. For that reason, the PD-120-906 number and the original component details should be reviewed before service work is planned.

Technician Service Tip

Technician Service Tip Compare the original control's terminal arrangement, mounting points, and any visible sensing bulb, capillary, or probe routing before replacement. Keep the sensing arrangement positioned as found unless the equipment documentation directs otherwise.

Common Failure Symptoms

• Cabinet temperature may appear unstable or slower to respond than expected.
• The refrigeration control sequence may not respond when temperature conditions change.
• Frequent cycling can indicate that the temperature-control circuit should be inspected.
• The equipment may continue running longer than expected and should be evaluated.
• The equipment may not begin a refrigeration response when expected, depending on the overall circuit condition.
• Damaged, loose, or discolored terminals can indicate that the control connection needs attention.
• A bent, damaged, or improperly routed sensing bulb, capillary, or probe may require inspection.
• Intermittent temperature response can indicate a concern with the control, sensing arrangement, wiring, or related components.

Commercial Applications

Commercial Applications This temperature control is identified for commercial refrigeration equipment and is relevant to commercial equipment service where temperature response and refrigeration control circuits require diagnosis. Foodservice maintenance teams, restaurant operators, refrigeration service companies, and commercial kitchen repair professionals may encounter this type of control during equipment service. Exact equipment fitment is not established here, so the equipment identification, serial number, original component, and verified OEM number should be reviewed before ordering. Do not rely on product appearance alone when selecting a temperature control for refrigeration equipment.

Before You Order

• Match OEM part number PD-120-906 to the original component and available equipment documentation.
• Compare the original component's terminal arrangement with the replacement information.
• Review the equipment data plate and serial number before ordering.
• Compare the mounting points and physical orientation of the removed control.
• Inspect any visible sensing bulb, capillary, or probe arrangement for routing details.
• Confirm that the part is being selected for the correct temperature-control function.
• Inspect connected wiring and terminals for damage or heat-related discoloration.
• Have a qualified service professional evaluate related control-circuit components when diagnosis is uncertain.

Related Components

• Sensing bulb or probe: Inspect the sensing arrangement and its routing because it works with the temperature control to detect equipment conditions.
• Control terminals and connected wiring: Compare terminal positions and inspect connections for damage, looseness, or discoloration.
• Relay or contactor: Evaluate related switching components because they may be part of the refrigeration control circuit response.
• Mounting hardware: Compare mounting points and hardware so the replacement control can be secured in the same position as the original component.

Frequently Asked Questions

What is OEM part number PD-120-906?

PD-120-906 is the verified OEM number for this single stage temperature control used in commercial refrigeration equipment.

What does a single stage temperature control do?

A single stage temperature control responds to the equipment sensing arrangement and changes its control-circuit state as part of the refrigeration temperature response.

Should I match PD-120-906 before ordering?

Yes. Match PD-120-906 to the original component and available equipment documentation before ordering.

What should be compared with the original temperature control?

Compare the OEM number, terminal arrangement, mounting points, component orientation, and any visible sensing bulb, capillary, or probe routing.

Can unstable temperature confirm that the control has failed?

No. Unstable temperature can indicate a concern with the control, sensing arrangement, wiring, relay, contactor, or another refrigeration-system component.

Is equipment fitment confirmed for PD-120-906?

Exact equipment fitment is not established here. Review the equipment identification, serial number, original component, and verified OEM number before ordering.
