Not sure what part you need but try lazada.
I had a German gate motor and the main board went and guys from a gate company said was 3000 bht to fix. It was around 7 year old and I said I can get a new motor for 4000 bht although Chinese made .
They stuck to price so I bought a new motor and had it installed and was fine for 4 weeks before it wouldn’t open one morning. Had people check it but couldn’t see what was wrong as it had electric and no sign of burn out anywhere, so I had call the original gate company. Guy came out and couldn’t see any problem but he changed main board at cost of 2800 bht ???????? and it worked. Few days later I seen same board on lazada for 900 bht !! Took him all of 10 mins to swap board over .
