Hi Everyone,
Two days ago I posted "VT-4000 in A-2000 fails after long periods of operation" in this forum.

I have run some temperature tests and made a modification. In one of the responses to my post a request was made of me to show what I did to solve the problem if I did. The problem is now solved and I have posted pictures online.

SEE:

After running temperature tests using a thermocouple and an old set point controller I had as a read-out I determined that the problem was a lack of ventilation around the VT-4000. I used an extra case cover I had to experiment with by cutting a hole in the side and installing a vent cover obtained for 99 cents fro a local building supply store. With only the power supply fan as the prime air mover I was able to keep the VT-4000 at around 68 F. / 20 C. for a twenty-four hour test period. The ambient temp was about 66 F. / 19 C. during that test. After that I covered the fan with tape and monitored the VT-4000 temp which went up to 97 F. / 36 C. in 30 minutes. I did not want to risk damaging the VT-4000 so I did not run the test to a fault. Who needs a toasted Toaster???

If you go to the above web page where I posted pictures for the previous topic mentioned above you can see the test in progress and the vent modification in the last four pictures on the bottom of the page. I strongly recommend a similar modification to any A-2000 with any model Toaster in it. As these things get older they become more susceptible to permanent damage by heat.

Thanks for the replies and suggestions.

You've successfully made the A2000 even uglier. :-D But, at least it's cool now.

Nice job Dave. Increased ventalation without adding fans. Too bad you can't find a cleaner grill. Something that looks less like it's suppose to be on the side of a house. :-D But hey, if it does the job, then looks are secondary.

Good job Dave, keep us in mind if you ever need extra effects for your Video Toaster system.
