Four-position Polydryer+ and Sanlu S4 combined dryer and dehydrator, compatible with AMS lite

Important Reminders:

• Remove the fan label before installing the fan. Prolonged exposure to the PTC may cause the label to melt and obstruct the air vent
• During assembly and testing, activate the fan first to ensure proper operation before testing the PTC heating element. This prevents the PTC from overheating
• If the fan fails to operate, press and hold OK to access settings: Set L to 5, H to 99, and C to 0. Avoid P-1 mode initially, explore it only after familiarization (ignore this if unfamiliar with P-1)
• The temperature control switch has two wiring configurations, detailed below. Connection may vary depending on the source of purchase. If the first method fails, try the second
• For amslite compatibility, consider printing my first design: amslite rotary shaft bracket. This beam support is recommended for the feed assembly (no additional hardware required): https://makerworld.com.cn/zh/models/550466#profileId-478972

Bill of Materials:

An 8-shaped power cord is also required. I did not purchase one separately. These cost around 1-2 yuan on PDD
