Ningguo Kingcool Import and Export Co., Ltd supplies Refrigerator Parts-Thermostat Manufacturers range together with a broad appliance and refrigeration parts programme. Our thermostat line covers mechanical, electric and network controls used in household refrigerators, window air conditioners, display cabinets and light commercial cooling equipment.
We operate as an industry-and-trade enterprise: we produce metalized polypropylene film capacitors on our own high-precision slitting and winding lines, and we act as an agent for air conditioner and refrigerator accessories. That combination lets us quote a thermostat together with the capacitor, motor, fan, control board or defrost component that sits beside it in the same unit.
What We Supply in the Thermostat Range
Our thermostat programme is built around the models most frequently requested by refrigerator and air-conditioning assembly, service and distribution customers. Each type is selected by sensing method, mounting pattern, temperature range and switching behaviour rather than by brand name alone.
- Mechanical thermostats — capillary and bulb sensing with a mechanical switch, used for refrigerator compartments and general cooling control.
- Electric thermostats — for heating and cooling equipment where an electrical control signal drives the switching element.
- Network and smart thermostats — for residential and commercial environments where a programmable set point and remote adjustment are required.
- Defrost thermostats and fuses — bimetal and thermal-limit devices that terminate defrost cycles and protect the circuit.
- Thermostat guards — enclosures that protect the control from tampering and mechanical damage in public or commercial installations.
Model Reference and Application Fit
The table below maps the thermostat models we list to their typical application and control style. It is the starting point for matching an existing part number or specifying a replacement for a new build.
| Model | Control Style | Typical Application |
|---|---|---|
| 077B6021 | Electric | Temperature control of heating equipment |
| TAM112 TAM Style | Smart / programmable | Home and commercial temperature control |
| RC14032-2 | Refrigerator thermostat | Refrigerator cooling circuit control |
| T229A74VET9 | Window A/C thermostat | Window air-conditioner temperature regulation |
| WDF23 | Network thermostat | Residential and commercial environments |
| 3ART5VC163 | Mechanical | Industrial and appliance temperature control |
| E2 Heating Style | Smart heating control | Modern home heating systems |
Thermal Design Behind the Thermostat
A thermostat only holds its set point when heat moves predictably through the assembly. Our structural approach treats thermal balance and heat leakage as design inputs, not afterthoughts.
- Conductive materials — copper and aluminium alloys are used at key heat-transfer points so heat reaches the sensing element quickly and the assembly stays light.
- Heat-dissipation structure — heat sinks, fins and fan-assisted paths increase surface area and improve air convection around heat-generating components.
- Thermal isolation — insulation separates high-temperature and low-temperature zones so each region stays inside its working band.
- Sealing and multi-layer insulation — O-rings, sealants and layered barriers limit air convection and radiation losses at the shell and interface.
- Temperature monitoring — high-precision sensors and control logic adjust the heating or cooling element to hold the set range and avoid unnecessary energy loss.
Configuration Choices We Confirm With You
Thermostats are rarely interchangeable across platforms. We configure each order against the physical and electrical envelope of your appliance or cabinet.
Sensing and Range
Capillary length, bulb dimensions, temperature range and differential are matched to the compartment or duct being controlled.
Electrical Interface
Contact rating, terminal layout, shaft or knob style and switching sequence are aligned with the existing wiring harness.
Mounting
Bracket, panel cut-out, fixing centres and guard requirements are confirmed so the part drops into the production line without rework.
Where the Thermostat Sits in the Wider Range
A thermostat is one node in the cooling circuit. Because we also supply the surrounding components, we can quote a complete kit rather than a single line item.
- Defrost Thermostat & Fuse — terminates defrost cycles and provides thermal protection.
- Refrigerator Control Board — the electronic layer that reads the sensor and drives the compressor and fans.
- AC/DC Fan — moves air across the evaporator and condenser so the thermostat sees a representative temperature.
- Refrigerator Parts — the full refrigerator accessory programme, from capillary tube to water filter.
Quality Control and Acceptance
Our capacitor production runs on high-precision slitting and winding equipment with real-time monitoring and automated warehousing and logistics. The same discipline is applied to the accessory lines we supply: incoming inspection, in-process checks and final performance testing before packing.
Thermostat testing covers thermal balance, heat leakage, temperature stability and switching behaviour. Where a project requires documented acceptance, we agree the test items and sampling plan with the customer before production and record the results against the batch.
Information We Use to Configure Your Solution
A precise quotation depends on a small set of project inputs. When these are available, we can match a model or propose a configuration without back-and-forth.
| Input | Why We Need It |
|---|---|
| Appliance type and model | Determines sensing style, range and mounting pattern |
| Existing part number or photo | Allows direct cross-reference to a listed model |
| Temperature range and differential | Sets the control band and switching behaviour |
| Voltage, current and terminal layout | Confirms contact rating and harness compatibility |
| Capillary or probe length | Matches the physical reach inside the cabinet |
| Order quantity and packing preference | Drives carton configuration and delivery scope |
Ordering, Packing and Support
We ship from Ningguo, Anhui, China, and our capacitor output already reaches the Middle East, Africa, South America and Southeast Asia. Thermostat orders follow the same export packing discipline: individual protection, labelled cartons and a packing list that matches the confirmed part numbers.
Because each employee works directly with the market, fragmented and personalised requests — a mixed carton, a specific model combination, a replacement for a discontinued control — are handled as normal orders rather than exceptions. Spare parts and repeat supply are quoted against the same reference data used for the original shipment.
Frequently Asked Questions
Can you match a thermostat to an existing refrigerator model?
Yes. Send the appliance model, the original part number or a clear photo of the installed thermostat with its terminals and capillary. We cross-reference it against our listed models such as RC14032-2 or 3ART5VC163 and confirm the closest match before quoting.
What is the difference between your mechanical and electric thermostats?
Mechanical models use a capillary or bulb sensor and a mechanical switch, which suits straightforward refrigerator and cooling control. Electric models, such as the 077B6021, use an electrical control element and are chosen where the switching is driven by a control circuit rather than direct mechanical actuation.
Do you supply thermostats together with other refrigerator parts?
Yes. We hold a complete refrigerator and washing machine accessory range and act as an agent for air conditioner and refrigerator accessories, so a thermostat can be ordered alongside defrost thermostats, control boards, fans, capacitors and installation materials in one shipment.
How is thermostat quality verified before shipment?
Thermostats are checked for thermal balance, heat leakage, temperature stability and switching performance. We agree the test items and sampling plan with the customer where documented acceptance is required, and results are recorded against the production batch.
Can you supply a thermostat guard with the control?
Yes. Thermostat guards are part of our air-conditioner parts range and are quoted with the thermostat when the installation is in a public or commercial space where the control must be protected from tampering or damage.
