Warning: I had to choose between a full control board swap or just replacing the relay on a 5 year old dryer
The dryer had a dead heating element. The relay on the main board tested bad, but the board was $180. A new universal relay was $12 and a 30 minute solder job. I went with the relay fix to save the customer money. It worked for about a month, then the board failed completely from another fault, and I had to go back for the full swap anyway. Has anyone else had a universal relay fix backfire, or is it usually worth the gamble on older units?
