A:AnswerProbably not required, but likely recommended, otherwise your vent pipe might over time start to develop odors from things like fish that would be neutralized by the charcoal filter. Check your owners manual to see if it has any recommendations. I just replaced my old internally vented one that didn't even have a charcoal filter installed, never really noticed a problem but did notice a bit of residue from the fan exhaust on the underside of my nearby cabinetry develop over time.
A:AnswerIf its the same size, most likely you can. Look at the overall dimensions and see if they are the same, and if they have the same kind of venting. My new GE was manufactured so I could configure the fan output to either outside through the top, outside through the back, or inside venting, just a couple screws and rotate the fan unit inside the housing to fit the kind of install you want to do.
A:AnswerMine had a little buzzing sound on one side when first installed that I fixed by tightening the mounting bolts and then wedging a bit of foam insulation in between the side and filler panel near where the sound was coming from, sometimes any appliance with a motor will just vibrate like that and anything that dampens that will fix the problem. Also, the blower fan might be running at the high setting, I'd check that. This model does have a fan that runs automatically but I think it has more than one speed.
A:AnswerYou might be able to find it on the internet by searching the model number or by going to an appliance parts dealer online, the manual itself may be an item on the parts list.
A:AnswerMy old plate was bigger than my new one. Are you sure you didn't mix them up? I tried the old greasy plate, and it definitely scraped the door.
A:AnswerWell I think it depends on how hot you want your drink. I put the cup of water for my tea for two minutes. You can lower to low med and high but it just as easy it put you cook time in.
