Re: [MBZ] OT RANT This makes me absolutely crazy
So this is a good question. I shut off the power to the unit for a coupla days or so (it was getting a bit warm in the house, but one of the other units was keeping it tolerable), restarted it. and all is good. I have new thermistors on the way so I guess they will be in reserve should it fail again. Maybe some sort of intermittent connection issue. I'm wondering if it might have been some water intrusion in the unit somehow, while I was gone Saturday it looked like there was a deluge so maybe the rain or excessive humidity or something got up in there. No idea, but for now I am happy. --FT On 7/11/22 5:43 PM, Randy Bennell via Mercedes wrote: AND . . . what caused the thermister to go bad and will it happen again? -- --FT ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] OT RANT This makes me absolutely crazy
AND . . . what caused the thermister to go bad and will it happen again? We played a similar game with a Breville Breadmaker. If my memory is correct, it too was a thermister. Breville has moved on and you cannot buy the part from them. I found a utube video where a fellow repairs the same unit as ours. He ordered a comparable part from Digi-Key and installed it. I followed suit and did the same thing. It worked for a couple of months and then did the same thing. My wife bought a new breadmaker - different brand - so I am not going to fix this one again. I am not enough of an electronics guru to figure out why this happened again after a few uses. We have a Breville toaster oven that appears to have suffered the same fate. Needless to say, we have given up on Breville appliances. Randy On 11/07/2022 4:34 PM, Floyd Thursby via Mercedes wrote: I have this mini-split system. Actually I have 3 of them, LGs.
