Hi we have recently installed a Samsung OTR microwave oven model no. smh8187wg, we chose option of vertical vent/exhaust, we removed the existing exhaust hood above range and installed microwave according to instructions. However when we turn the otr vent fan on, there is a front grill (on the microwave) that opens and air blows out, the microwave is sucking from the bottom pretty good, I checked the vent flap on top of microwave and it is free, also we disconnected the vent connection at microwave top and checked- some air is blowing out but most of it comes out at the front, and all the fumes from cooking just seem to be recirculated, this doesn't seem normal to us, even when microwave is being used this front vent opens. My question is how can we disable the front vent, we called the dealer and they said to contact samsung. we did and still waiting for their reply.

I just installed a samsung microwave and it came with the fan set for recirculate. I moved the fan motor for top exhaust. Had to go back to Home Depot to get a broan exhaust damper/adapter. It slides in the top of the microwave and sticks out about a 1/2". You put a 3 1/4" by 10" exhaust onto this then you can transition to round etc... Be careful you need about 3" of 3/1/4 x 10" exhaust section so the damper does not hang up.
The vent fans can be moved to three different positions. Top exhaust, back exhaust and front exhaust. Take the microwave down. There are two screws on the vent cover, take those out and bend the vent cover up. remove the one screw in the back holding the vent fans in. You can now lift the vent fans up and turn then to the right position.

Sounds like the magnetron is overheating. There is an automatically-resetable thermal circuit breaker attached to the magnetron. Most likely your problem is caused by either a cooling fan that is not running, or is running too slow (caused by gummed-up bearings). In some over-the-range (OTR) microwave ovens, the exhaust fan is run at a slow speed to cool the magnetron, and if it's bearings get gummed up, it won't run on the slow speed. But if it's a new OTR microwave, then the exhaust fan may be pointing the wrong way. (It is rotatable, depending on the installation). For example, if it is pointing up, but you don't have an exhaust vent over the microwave, then the air has nowhere to go, and the magnetron will overheat.
Is this a countertop microwave or an over-the-rang (OTR) microwave? If it's a countertop model, you need to completely remove the outer case to get to the lightbulb. If it's and OTR microwave, there usually is an access cover located behind the grill vent. You can remove that grille vent by removing the 2 to 4 screws above the grill vent. Then either slide the grill vent 1/4" to the left to remove it, or else (depending on the model), just pull out the top of the grill vent, followed by the bottom. Then you should be able to see the lightbulb access cover. Usually there is 1 screw that you have to remove. But unplug the microwave before you to any further! Now remove the screw, lift up and remove the cover, and you should be able to get to the light bulb.
First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse. Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open. remember use VOM. God bless you

what problem do you have mention ? attached is there a list please indicate. God bless you
No Lights or Power, Unit seems Dead The voltage to the unit is good.Lights come on, but can not program unit, Touchpad dead Microwave Runs, but no Heat Turntable rotates, acts like it is heating but doesn't. This is the big one, many possibilities. Microwave Runs, Heats, but turntable does not move Microwave is arcing Microwave Vent Hood is not working Over The Range(OTR) Models. Microwave Stove Light not Working OTR models, light bulbs good. Microwave overheats and keeps turning off
Brackets can remain the same throughout a particular brand for several years but will also change every year at times. Same year and same brand, I would say yes. Different year of manufacture or different brand name I would say, no it will not fit the existing brackets. If you have a particular brand in mind and have the model number of the existing OTR, it is usually possible to search out installation instructions for both at the manufacturer's website. You could then compare to see if they will match up. The two screws through the upper cabinet floor into thr top of the OTR can vary, within a particular brand even in the same year of manufacturer.
