问题：开启过多加热元件后出现 错误代码 26 或 42。
潜在故障：电子板损坏
具体情况：在几周的时间里，先是在开启超过 3 个元件后出现错误代码 42，随后只要开启 2 个，最后是 1 个，直到所有加热元件都无法开启。
根本原因：主电子板上的电解电容老化/击穿。
解决方案：
- 关闭电源（断路器）——注意灶具内部有高压
- 将灶具从台面开孔中取出并滑至平整表面
- 使用 Torx 螺丝刀拆下金属外壳周围的所有螺丝
- 小心将玻璃面板的前部从外壳中倾斜取出，注意后部有电气连接，并将玻璃面板的后部放置在稳定的表面上。你可能需要他人的协助。
- 在再次确认断电后，记录连接到玻璃组件的四根电线的颜色编码（从左到右依次为绿色-地线、白色、黑色、红色）
- 接下来，拆下四颗 Torx 螺丝，打开黑色塑料盖板。
- 小心拆下左侧连接器上连接到显示屏组件的塑料排线。
- 小心拆下由塑料卡扣固定的继电器与电容电路板。
- 如果其中一个电容顶部鼓包或有损坏迹象，更换它或许能修复设备。拆焊故障电容需要一定的工具和技能。更换的电容容量和电压需至少达到原规格，且必须使用耐高温 105 °C 的版本。否则，你将不得不更换整块电路板，而不是仅仅更换一个 2 美元的元件。
- 重新组装，完成。

Great fix. Fixed my cooktop for $4 in parts plus $12 for the soldering iron.
My same model cooktop showed similar symptoms, except like Capt Kirk fading from one universe to the next, it appears my (flux) capacitors were fading in and out of the working universe. Both my 470 microF capacitors were bulged and very slightly leaked.
Circuit board work is not my strong suit - I can sweat pipe, but those tiny connections with heat sensitive components are hard. Nevertheless I managed to get the old ones out and put two new ones in.
I'm not sure who I'm thanking, but Thanks!

Being the unknowing person that I am where did you find the caps? bonitajay@comcast.net

Really appreciate the tip. Ordered 2 caps (even though only one was bulging, I replaced both) of same dimensions. Replacements came and were 5MM shorter than represented, but same specs so hope they work for the long term. The replacement complete circuit board module is about $400 I was told. Thanks again - am now going to do the same with a motherboard in my tower that failed with 4 fat caps!

Excellent advice, worked out perfectly. I changed all the electrolytics on the board, took a while to source the parts (due to the clearances required) but figured they will all split sometime down the road. Had to settle for the 105C components but hopefully they will work out.
Thanks again.
Happy cooking!

Thank you so much!!! Appliance store said nothing they could do to fix cook top. So, we were ready to replace circuit board for ($ 500.00) or buy new cook top ($ 1,000.00) when we decided to try to replace the capacitors. We couldn't find the parts (capacitors) locally so we order them on Amazon. So far so good worked perfectly! Again thank you so much!
:) Happy Cook!!!!
