I recently had installed a new hot air furnace, that also has an Evaporator section in it for the house air conditioning.
It is a: Trane TUD 120 R 9V5K
Last night, a thunder storm passed thru the area.
Nothing really major; have certainly seen worse.
A bit of lightning, etc.
Lights flickered for a few seconds.
This is the first time since the new installation that we had this type of storm.
Anyway, the main circuit board in the furnace fried.
Surprisingly, nothing else in the house suffered any damage, whatsoever.
Even the PC's still work. Of course most of the other items
in the house are plugged into power extension strips with overvoltage and spike protection; perhaps this saved them ? Hard to know for sure, though.
The furnace (110 V) is, of course, hard wired to the house wiring via a dedicated circuit breaker.
My questions are:
Are these Trane circuit boards overly succeptible to these types of things and/or are they known to get fried "fairly often" ?
Would really hate to have it happen again.
Is there any kind of circuit breaker we can change to that has this spike and overvoltage protection ?
Or, what might you folks recommend ?
