Modding of GGF Micro
« on: September 14, 2017, 04:50:01 AM »
Hi everybody,
I have a Fimar Micro1c oven which is basically a GGF Micro, with glass door.

I bought it last winter and I'm happy of it especially because I paid it less than half its official price, second hand and only used a few times by its first owner. First mod I made was to apply a 3.2cm biscotto from "fornace Saputo" of Casapulla.

Pasts week I ordered a 2100W Fagor 74X2310 top heating element which is on its way. The point is that once I disassemble the oven I would like to improve its insulation, and once I buy some insulating fiber I would also like to insulate the door by applying a stripe of insulating woolrock on the glass and blocking it with a metal plate which I plan to solder to the door.

Then I have two questions:
- any suggestion on the insulation to use?
- did anyone ever do any of the mod I planned?

Thanks everybody!

Hello.

I haven't done work on the Micro 1c specifically but (and after reading plenty about the GGF/Fimar/Effeuno) I picked up a GAM MD1 and replaced the upper element (800W > 2000W), swapped out the thermostats (350>500C), and replaced most of the insulation (which was some sort of basic ceramic fiber) with Morgan Thermal Ceramics bbio-soluble "Superwool Plus". It seems to be available on Ebay but i got it from a local company here. It was about $50 for 7 meters (but this is not a to consumer price). It's a lot denser than the ceramic wool.

The Micro already is equipped with 500C thermostats so presumably the insulation is sufficient but if you want to upgrade it, it's probably best to remove/replace the current insulation. The Superwool does a good job, but it does still get hot on top and on the side, and you don't want to lose any existing airspace (someone on an italian forum double wrapped the oven and ended up with a hotter exterior). At these temperatures, the control compartment sits around 45 degrees usually (about 20 over ambient).

I've seen some people voicing concerns about the need for improved wiring, but everything in the GAM, and the Micro looks the same, is 16AWG which is sufficient. Is the door double pane glass? I got the idea from someone (maybe Sub?) to jam some insulation in between the panes. Won't solder melt at those temperatures? I have no idea about that stuff.

You've probably seen this but it gives an idea about what you might find inside. http://laconfraternitadellapizza.forumfree.it/?t=67488240

THe whole thing was a real challenge but worth it. 60 second pizzas are easy now. Any questions I'd be happy to help out.

Thanks for the hint, I'll see if I find something similar here too.

umh... then I'll probably install the new upper element and give it a try to see how hot the exterior becomes. I mean dismounting the oven doesn't look such a hard job.

No, the door isn't double pane glass. And yes, I suspect solder could melt, I need to think a bit more about how to improve door insulation. And once again maybe just replacing the upper element is enough to get lower than 90sec for a pizza.

Thanks for your help! I'll share the updates in the next days.

If you use the often suggested Fagor element I'd say easily. The chamber in mine is just 8cm but 90sec is nothing now. 60 is easily achievable (around 475 degrees). With a 2k top element and by raising the stone that'll probably be sufficient. Look forward to seeing how it goes!
