I am trying to figure out what's wrong with my G.E. Downdraft Vent. It use to work fine and then today the breaker in the house panel flipped off. I then flipped the breaker back on after unplugging the Vent. When I plug in the Downdraft Vent back in the Breaker Flips off again on the braker panel. When I turn the breaker back on and plug in some other device like a blow dryer or the stove top thoses device run fine. So far I have concluded that my electrical outlet is OK. I then premataturly replaced the power cord on the downdrat vent thinking I had a bad power cord. Well that did not fix the problem. I now think I have a bad Gear Motor that controls the up and down motion of the Vent that is causing the breaker to blow. the reason I say that, is when I disconnect the power cord pigtale from the Gear Motor the breaker stays on. I have order a new Gear Motor but I want to make sure that that is the problem. Can anyone confirm I am marching down the right path.

Sounds like your diagnosis is right, especially because the limit switches which could cause the short too are coming with the gear motor as an assembly.

Well, I replaced the Gear motor assembly, which did fix the orginal problem, of the breaker flipping. Now, what is happening, is when I plug the downdraft in the power source the down draft vent continues to go up and down. The on/off switch on the top of the unit does not seem to stop it therefore, I have to unplug. It really funny to watch this thing go up and down. Of course, now my wife doubts my repair capabilties and I must now redeim myself. I now think that the control board got fried when the breaker kept blowing. I guess there is some logic that comunicates with the switch to stop it from going up and down. I took one of the old switches off the old motor assembly to check to make sure my new part didn't have a bad switch. The problem did not go away. So I have concluded that it has to be the control board that is bad. Can anyone confirm my deduction so i can feel better that I ordered the right part to fix the problem. Thanks Mike

Thanks Gene for your reply. I did notice that one of the swithces on the old motor assemlby had a piece of plactic that had broken off and was probably causing the short.
