含义
E61 故障代码表示干衣机加热器继电器电路出现故障，控制系统无法正常接通加热元件的电源。此代码通常在启动加热循环后几秒钟内触发，当控制板检测到继电器驱动信号与加热器实际状态不一致时报告。干衣机仍可运转但无加热，导致无法烘干衣物。
常见原因
- 加热器继电器线圈开路或短路，无法吸合或持续吸合。
- 继电器触点烧结粘连，导致加热器持续通电不受控制。
- 继电器驱动三极管或 MOSFET 击穿，控制信号无法到达继电器线圈。
- 加热器本身断路（电热丝烧断）或热熔保险丝熔断，控制板误判为继电器故障。
- 主控板焊点开裂或继电器插座接触不良，间歇性断连。
自助排查
- 断开电源，打开机壳找到加热器组件，用万用表电阻档测量电热丝两端通断；若为无穷大则电热丝烧断需更换。
- 检查串联在加热回路中的热熔保险丝是否熔断（用万用表通断档），若熔断需排查过热原因后更换。
- 找到加热继电器，在启动烘干程序时用万用表测量继电器线圈两端是否有 12V 或 24V 驱动电压；无电压则主控板驱动电路故障。
- 用万用表测量继电器常开触点两端在吸合时应导通，断开时应无穷大；若始终导通则触点粘连。
- 检查主控板上继电器相关焊点是否有环形裂纹，必要时补焊或更换主控板。
English
Meaning
Error code E61 indicates a fault in the dryer’s heater relay circuit — the control board cannot properly engage power to the heating element. This code typically triggers seconds after the heating cycle starts when the board detects a mismatch between the relay drive command and the actual heater state. The dryer may tumble normally but produces no heat, making it unable to dry the load.
Common Causes
- Heater relay coil open or shorted, preventing the relay from pulling in or staying engaged.
- Relay contacts welded or stuck together, causing the heater to remain powered uncontrollably.
- Relay driver transistor or MOSFET failed open, blocking the control signal from reaching the relay coil.
- Heating element burned open or the thermal fuse blown, causing the control board to misinterpret the open circuit as a relay fault.
- Cold solder joints on the main board or poor contact in the relay socket causing intermittent disconnection.
Self-Check Steps
- Disconnect power, open the cabinet to access the heater assembly, and measure continuity across the heating element terminals with a multimeter — infinity indicates a burned-out element requiring replacement.
- Check the thermal fuse in series with the heating circuit for continuity; if blown, identify and resolve the overheating cause before replacing.
- Locate the heater relay and, with the drying cycle running, measure for 12V or 24V DC across the relay coil terminals — no voltage indicates a control board drive circuit failure.
- Test the relay normally-open contacts: they should show continuity when the relay is energized and open (infinite) when de-energized; continuous continuity indicates welded contacts.
- Inspect solder joints on the main board around the relay driver section for ring cracks; reflow or replace the board as needed.
