I think the electronics are in the head of the machine not in the base.

Recently bought the entry level Pfaff machine and was told to NEVER use the air that it would ruin my machine.

Well my computerized Singer Quantum uses air to run the foot control. The air is going into or out of the machine, haven't figured that out. It's not a good idea to keep compressed can air in your home anyway. It's deadly if inhaled.

Has any one had a Circuit board go out in there machine.

I took my baby lock Decorator's Choice in for I had it start to beep and show an error code of f01, the dealer said that the Circuit board went out. He would have to order it. He said they are hard to put in and Baby Lock has a 5 year warranty on the part but not the labor. So he told me it would that would be about $120.00 for labor. He has had it a week and haven't heard a word. I know someone else that had the same thing happen on there Bernina and it was $600 to repair it.

5 years ago I watched the one and only time my machine was cleaned. He used an air compressor. I watched where the oil went.
I have an air compressor so I take it apart and then outside. Blow the lint out and a drop of oil.
Sorry but I cannot explain where the oil goes.

Air compressor is different than canned air. I used canned air on my keyboard and it left a film of oily something that I could never get off completely and it collected dust like a magnet. I would never use it inside a machine or on my keyboard again.

I use a brush to get out the big fluff and then compressed air for anything that the brush couldn't reach. I've been doing my machine maintenance this way for years and, this is going to get me in trouble, have never had a problem. I have four machines and do the same on all, have never had a machine in the shop. You know what they say about tempting fate? Well I figure I've just made a big boo boo.

I was told my a longarm repairman NOT to use the canned "air" that is sold for computers for this reason on my longarm and also another reason not to use it on my Elna--that the canned stuff is not really air--but is canned gas and that it not only is oiled and collects dust, but also will attract moisture in the air--certainly not needed in a machine! So he suggested if I can truly find canned AIR to use on my long arm,to go ahead--otherwise I can use our air compressor (not practical) a bike pump, or better yet, the vacumn cleaner. And he suggested only a vacumn for my domestic machine cause I wouldn't want to blow bits of stuff into the case where it lodges in moving parts. Now my cheaper, traveling machines that are not computerized and I can take apart are another story! I've looked but can't find true canned air, so plan to buy one of those little specialized attachment hoses for my vacumn to clean my machines (think Keepsake catalog has them??)

Here's a good article about using canned air http://bearhugquiltworks.blogspot.co...s-to-wise.html

they really aren't good for computers
