I had a service guy tell me that sometimes electr. boards fail inside

protector just for the clothes dryer? Thoughts on this...

Hi,
Sorry to say that your idea is baseless and funny. Board has protection
circuit built-in but when powerful surge(spike) comes down, anythng can
get damaged no matter what protection you have. I often see board
failures caused by heat due to under-rated cheap component or cold
solder joint(s). Repairing is not easy because they use ASIC in
many cases which is difficult to obtain.
