Product Overview

OEM Part Details Manufacturer: Everest OEM Part Number: RS04-00 Part Type: Defrost Termination Thermostat OEM Status: VERIFIED Product Overview The Everest RS04-00 defrost termination thermostat is an OEM temperature-control component used in commercial refrigeration control circuits. Its job is to respond to the temperature condition reached during a defrost cycle and support the control sequence that brings defrost to an appropriate end. That function matters because defrost operation must work in coordination with the cabinet's refrigeration controls rather than continue longer than necessary. In a commercial refrigeration cabinet, a defrost termination thermostat helps the equipment manage frost removal while supporting a return to normal cooling operation. When this component is damaged, has terminal concerns, or no longer responds correctly, the control circuit may require qualified diagnosis before a replacement is selected. The RS04-00 is identified as an Everest OEM part, giving service teams a reliable manufacturer part number for comparison with the removed component and equipment information. For restaurant cold storage, prep refrigeration, and foodservice equipment service, correct control components help technicians address refrigeration-control concerns without guessing at part identity. Compare the original component carefully, confirm the RS04-00 number, and review the equipment data plate and serial number before ordering.

Product Function

Product Function This defrost termination thermostat serves as a temperature-responsive switch within a commercial refrigeration defrost control circuit. During a defrost sequence, it helps the circuit recognize the temperature condition associated with defrost termination. The component therefore supports coordination between defrost activity and the equipment's normal refrigeration operation. Because it is part of a control and safety circuit, the thermostat should be evaluated as part of the connected circuit rather than treated as the automatic cause of every defrost or cabinet-temperature concern. Qualified service personnel can compare the original part number, terminal arrangement, sensing-element condition, and connected controls before replacement. Using the verified Everest RS04-00 number helps reduce incorrect part selection when the removed thermostat matches this OEM identification.

Why Choose a Genuine OEM Replacement?

Why Choose a Genuine OEM Replacement? The Everest RS04-00 is identified by its verified OEM part number, which gives technicians and purchasing teams a clear reference when replacing the original defrost termination thermostat. Matching the manufacturer part number helps keep the order focused on the correct identified component instead of selecting a look-alike control based only on appearance. Compare the removed part, its terminals, and the equipment data plate before purchase to support confident commercial equipment service.

How This Part Works

How This Part Works A defrost termination thermostat works through temperature response. In the defrost control sequence, the thermostat senses the condition at its installed location and changes the circuit state when its operating condition is reached. That response is used by the refrigeration control circuit as part of the transition between defrost activity and normal cooling operation. The thermostat does not operate independently of the rest of the cabinet. Wiring terminals, the sensing element or routing where present, connected controls, and related defrost safety controls can all affect how the circuit responds. A cabinet that has frost accumulation, unusual control behavior, or temperature concerns may have more than one contributing condition. For that reason, the Everest RS04-00 should be installed only after qualified diagnosis confirms that the thermostat is the appropriate component to replace.

Technician Service Tip

Technician Service Tip Before removing the original thermostat, document its part number, terminal arrangement, installed orientation, and sensing-element routing where present. Inspect the connected terminals and related control components for damage or loose connections. A qualified technician should evaluate the defrost control circuit before replacing a temperature-responsive control component.

Common Failure Symptoms

• Frost accumulation that may indicate the defrost control circuit should be inspected.
• A defrost cycle that appears to continue unexpectedly may indicate a temperature-control concern requiring diagnosis.
• Cabinet temperature recovery concerns following defrost can indicate that related controls should be evaluated.
• Unstable refrigeration control response may indicate a concern with the thermostat or another connected component.
• Damaged, corroded, or loose thermostat terminals should be inspected as part of the control circuit evaluation.
• A damaged sensing element or damaged routing, where present, may indicate the thermostat requires closer inspection.
• Repeated refrigeration-control interruptions can indicate that related safety controls and wiring should be evaluated.
• A thermostat that does not correspond to the removed OEM component may indicate a prior incorrect part selection.
• Visible heat damage at connected wiring or terminals may indicate a circuit concern that requires qualified service.
• Defrost-related operating concerns can indicate that the thermostat, connected control board, and related controls should be inspected together.

Commercial Applications

Commercial Applications The Everest RS04-00 defrost termination thermostat is identified for commercial refrigeration control use. Commercial refrigeration equipment is commonly maintained in restaurant cold-storage areas, prep refrigeration lines, foodservice kitchens, and service operations responsible for refrigerated cabinets. Its role is associated with the defrost control circuit, where temperature response helps support the sequence between defrost operation and normal refrigeration operation. Specific equipment fitment is not stated here. Confirm the Everest RS04-00 part number against the original component and review the equipment data plate and serial number before ordering. Qualified refrigeration service is recommended when diagnosing defrost-control or cabinet-temperature concerns.

Before You Order

• Match the verified Everest OEM part number RS04-00 to the original component.
• Compare the removed part's overall configuration with the product image and product title.
• Confirm the manufacturer is Everest before selecting this OEM thermostat.
• Review the equipment data plate and serial number for service identification.
• Compare the terminal arrangement and connected wiring before ordering.
• Inspect the sensing element and its routing where present on the original component.
• Compare the original component's installed orientation and mounting arrangement.
• Have a qualified technician evaluate the defrost control circuit when the source of the operating concern is uncertain.
• Inspect the connected control board and related defrost safety controls for conditions that may affect circuit response.

Related Components

• Wiring terminals and connectors should be inspected because damaged or loose connections can affect the thermostat's control-circuit response.
• The sensing element and its routing should be compared where present, since damage or an incorrect placement can affect temperature response.
• The connected control board should be evaluated because it works with the thermostat as part of the refrigeration control circuit.
• Related defrost safety controls should be inspected because multiple control components can influence defrost sequence operation.

Frequently Asked Questions

What is the Everest RS04-00?

The Everest RS04-00 is an OEM defrost termination thermostat used in a commercial refrigeration control circuit.

What does a defrost termination thermostat do?

It responds to temperature conditions during a defrost sequence and supports the control circuit's transition between defrost activity and normal refrigeration operation.

How do I confirm that RS04-00 is the correct part?

Match the Everest RS04-00 number to the original component, compare the terminal arrangement and configuration, and review the equipment data plate and serial number.

Can frost buildup mean the defrost termination thermostat needs replacement?

Frost buildup may indicate that the defrost control circuit should be inspected, but qualified diagnosis is needed because connected controls and wiring can also affect defrost operation.

Should I inspect wiring when replacing this thermostat?

Yes. Inspect connected terminals and wiring for damage, corrosion, loose connections, or heat damage that could affect control-circuit response.

Does this listing confirm equipment fitment?
