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.

Compressor Parts Buying Guide: Selection Points, OE Cross Reference, MOQ and FOB Terms

Compressor parts are small, cheap and critical: a failed PTC relay or overload protector stops the whole cooling system. Because compressors themselves are heavy and expensive to ship, the surrounding start and protection components carry most of the after sales volume. This guide explains selection, cross reference and trade terms for this category.

Selection Points for Compressor Parts

Parameter	What to Check	Why It Matters
Relay resistance value	Match the ohm rating printed on the PTC element	Wrong resistance prevents compressor start or trips the protector
Rated current	Protector amperage matched to compressor LRA and FLA	Undersized protectors trip during normal start surge
Capacitance	Start and run capacitor microfarad value and voltage class	Weak capacitors cause hard starting and humming
Coil voltage	12V, 24V or 220V for solenoid valve coils	Overvoltage burns coils within hours
Terminal layout	Pin count, spacing and housing shape	Decides plug and play fitment on the compressor shell

Start kits, combining relay, protector and capacitor, move fastest in markets with unstable grid voltage because they resolve most no start complaints in one replacement.

OE Number Cross Reference Method

Read the part number from the relay or protector body, for example QP series or 4HP types.
Note the compressor model from its nameplate, brands like Gree, Midea, Haier and LG reuse standard kits.
Measure pin spacing and count, common layouts are 2 pin and 3 pin with 12.7 mm spacing.
For capacitors record microfarad value, voltage class and case diameter.
Send photos of the original parts and the compressor nameplate for a matched kit quotation.

MOQ and FOB Terms Explained

MOQ for compressor parts is 300 to 500 pieces per model because unit values are low, with trial orders from 200 pieces and mixed models allowed to fill a carton. FOB, free on board, means the USD price covers goods, export clearance and loading at the China port, freight and import duties are on the buyer. Tiered reference prices for 1-4, 5-19 and 20+ pieces are published per product page and confirmed in writing on quotation.

Frequently Asked Questions

Question	Answer
Do relays fit across brands?	Standard PTC relays interchange widely when resistance and pin layout match; inverter compressor boards do not.
What warranty applies?	12 months from shipment date, with function sampling before dispatch.
Can I mix relays, protectors and capacitors in one order?	Yes, mixed model shipments are allowed from the trial MOQ.
Are 12V and 24V coils both stocked?	Yes, solenoid valve coils are listed by voltage with OE references on each page.

Conclusion: match compressor parts by resistance, rated current, capacitance and pin layout, and prefer start kits in markets with unstable power. The compressor parts category shows live stock with tiered FOB reference prices and MOQ, and matched quotations are returned within 24 hours via sales88@ggatc.com or WhatsApp +86 181 5864 9251.
