What is the minimum order quantity (MOQ)?

MOQ starts from 50 - 100 pieces for most drain pumps, magnetrons and motor parts, and from 200 pieces for control boards and sensors. Mixed-model trial orders are accepted to help you test the market before scaling.

How long is the lead time?

Stock items ship in 3 - 7 days after payment confirmation. Made-to-order batches take 15 - 25 days depending on quantity and packaging requirements. Peak season (Aug - Oct) may add 5 - 7 days.

Do you support OEM packaging and labeling?

Yes. We provide neutral packaging, custom color boxes, your logo printing and barcode labeling. OEM packaging usually requires 500 - 1,000 pieces per model and 5 - 7 extra days for printing.

What warranty do you offer on spare parts?

Standard warranty is 12 months from shipment date for motors, magnetrons and control boards, and 6 months for consumable items such as carbon brushes and filters. Defective rate above the agreed threshold is replaced or credited in the next order.

Which shipping methods do you handle?

Express (DHL/FedEx/UPS) for samples and small parcels, air freight for urgent 50 - 300 kg orders, and sea LCL or FCL for wholesale volumes. We support FOB Shenzhen, FOB Ningbo and CIF terms, and can consolidate multiple categories into one container.

What are your payment terms?

T/T with 30% deposit and 70% balance before shipment is standard. PayPal and Western Union are accepted for sample orders. For repeat buyers we can discuss O/A terms after several successful shipments.

Are these original brand parts?

No. All items are compatible aftermarket replacement parts. Brand names such as Midea, Gree, Haier, Little Swan, LG, Samsung, Whirlpool and Panasonic are used only to describe fitment. All trademarks belong to their respective owners.

Can you match parts by OE number or photo?

Yes. Send the OE number, the nameplate photo of the appliance, or a photo of the old part with dimensions to sales88@ggatc.com or WhatsApp +86 181 5864 9251. Our team replies with matched models, price and availability within 24 hours.

Do you provide samples?

Samples are available. Sample cost is refundable against a bulk order above the agreed quantity. Buyer pays courier freight, or we add it to the sample invoice.

What documents can you provide for customs clearance?

Commercial invoice, packing list, bill of lading, certificate of origin (Form A / Form E where applicable) and CE or RoHS declarations for eligible items. Tell us your import requirements when confirming the order.

Appliance Parts Selection Guide: How to Match Drain Pumps, Magnetrons and Motor Parts by OE Number

A practical matching workflow for importers and repair shops: read the OE number, verify electrical parameters, confirm mechanical dimensions and cross check compatible models before ordering.

Appliance Parts Selection Guide: How to Match Drain Pumps, Magnetrons and Motor Parts by OE Number

Wrong parts are the most expensive mistake in appliance after sales. A mismatched drain pump or magnetron creates return freight, warranty disputes and lost shelf space. This guide explains the four step matching workflow used by professional importers when sourcing white goods spare parts from China.

Step 1: Capture the OE Number Correctly

The OE number is printed on the part body, the appliance nameplate or the service manual. When the label is damaged, record three physical facts instead: electrical rating, mounting geometry and connector type.

Photograph the part label at an angle to reveal embossed characters.
Photograph the appliance nameplate, which lists model and voltage.
Measure the mounting hole spacing with a caliper, not a ruler.
Count connector pins and note the terminal width in millimetres.

Step 2: Verify Electrical Parameters

Electrical parameters decide whether a replacement part will run safely. The table below lists the parameters that must match for the three highest volume categories.

Category	Must Match	Tolerance Allowed	Typical Failure If Wrong
Drain pump	Voltage, frequency, power	+/- 10% power	Pump stalls, water stays in tub
Magnetron	Output power, filament voltage, frequency	Filament +/- 0.1V	No heating, HV fuse blows
Motor part	Voltage, insulation class, speed, shaft diameter	Speed +/- 5%	Overheating, belt slip, board fault code
Compressor relay	Resistance value, rated current	Resistance +/- 1 ohm	Compressor will not start
Control board	Input voltage, connector pinout, program set	None	Board does not power on

Step 3: Confirm Mechanical Dimensions

Dimensional data prevents cabinet interference. Record outlet diameter and flange type for pumps, bracket hole pattern for magnetrons, shaft diameter and stack length for motors, and capillary length for thermostats.

Drain Pump Dimension Checklist

Inlet diameter: 25 mm, 32 mm or 38 mm.
Outlet diameter: 20 mm, 22 mm or 24 mm.
Mounting: 3 screw flange, twist lock or rubber grommet.
Overall height clearance inside the base pan.

Step 4: Cross Check Compatible Models

One part number often serves several appliance models across brands. Before placing a bulk order, ask the supplier for the compatibility list and confirm at least two of your own service records appear on it.

Part Type	Average Models Covered	Cross Brand Reuse	Stocking Advice
Universal drain pump	12 - 25 models	High	Keep 2 - 3 SKUs covering 80% of jobs
Magnetron 2M214	18 - 30 models	High	Single SKU plus HV capacitor kit
Carbon brush pair	40+ models	Very high	Buy in 500 piece packs
Main control board	3 - 8 models	Low	Order per model, avoid overstock
NTC sensor	20+ models	High	Bundle with heating element orders

Conclusion: match by parameter first and by brand name second. A disciplined four step workflow reduces wrong part returns from an industry average of 8 - 12% to below 2%, and lets a repair shop cover most jobs with fewer than 40 SKUs. When in doubt, send the OE number and a photo to sales88@ggatc.com or WhatsApp +86 181 5864 9251 for a matched quotation within 24 hours.
