Hi.
I had the control board of my dishwasher replaced 2.5 months ago after 4 yrs of service. 4 weeks later, the thermal fuse blew with evidence of a number of wires getting hot (the insulation on the door was slightly deformed/melted in places). The service tech came out and replaced the fuse and left (we had a 90 day warranty on the repair). All was good for 5 weeks - but we did avoid sanitize and heated dry out of paranoia.
Today, it happened again. The tech came out and replaced the thermal fuse (again, within 90 days of original repair). My wife watched him, and said he did not replace the thermal fuse harness - which the service sheet under the dishwasher says you must do.
He made a comment about our house power being the cause, power surges etc... Now, I find this hard to believe for the following reasons: 1) the dishwasher is the only item on that circuit and it has lasted 4 years. 2) I have many computers and other electronics on all the time that have never "fried" (as he puts it).
So I ask the forum, is he on to something? My basic understanding of the thermal fuse is that the dishwasher is pulling too much energy (motor going bad for example) which overheats the wires. A Thermal fuse would not protect against a power surge. Is this correct? I could also be 100% wrong.
I have another fuse+ harness coming in, as I do not want to buy a new dish washer right now.
Any other thoughts? Is this just a symptom of modern electronic appliances?
Thanks
(sorry for the lengthy post).
