Question about Samsung SMH7178STD Microwave Oven

Open Question

Smh7187 exhaust fan

My microwave/hood has a 400 cfm exhaust fan but it does not seem to be very efficient. There is a motorized cover over the grillwork which opens when the fan is on. A lot of air is drawn in here, and not much seems to be drawn from below. Can this grillwork be partially blocked to increase drawing power of the exhaust fan? The fan is correctly installed, and vented through an outside wall.

SOURCE: Samsung otr microwave vent problem

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.

  1. Exhaust fan motor If your exhaust fan motor is not running, there are a couple of things that you can check involving the motor to locate the problem. After removing the fan motor, you can manually attempt to turn the fan blades with your hand. If the fan motor is working properly, the blades should spin effortlessly. If this does not occur and the blades are taught, the motor will need to be replaced. Secondly, the fan motor itself can burn out due to time and usage. Using an ohm meter, the exhaust fan motor should read open for continuity. If it does not, then the fan motor has expired and will need to be replaced.
  2. Thermostat Another part that could cause the microwave exhaust fan to not work is a faulty thermostat. A thermostat gauges the air temperature, which activates the exhaust fan when required. If this part becomes flawed, the exhaust fan will not energize and the thermostat will need to be replaced.
  3. Main control board If your exhaust fan is still not working and the microwave fan motor, wiring, and thermostat are operating accurately, the root cause could be with the main control board. Replace the main control board.

Exhaust Fan Motor


If the exhaust fan does not run the fan motor might be bad. Remove the fan motor from the microwave oven and see if the blades can be turned by hand. They should turn very freely, if they're stiff the fan motor will need to be replaced. The fan motor can also burn out. To test this use an Ohm meter. The motor should have continuity. If it doesn't, replace it.
Thermostat


If the microwave exhaust fan is not working the thermostat might be defective. The thermostat senses the air temperature and turns on the fan as needed, if it's defective it won't turn on the fan. Watch our video on testing thermostats.
Main Control Board


If the microwave exhaust fan is not working check the exhaust fan motor and wiring. If they are good the main control board might be defective.1_24_2013_5_50_54_pm.gif1_24_2013_5_53_00_pm.jpg

I have a Maytag microwave, model# MMV5165BA and it has no heat.Everything displays and vent works but no heat.Can you suggest anything before I toss it out?


If it operates as normal but items don't seem to get hot it probably is a Magnatron failure (microwave producer). More times than not the repair / replacement of a Magnatron these days is not worth the investment, especially if the microwave is 4 years old or older ! You should be able to replace your microwave with a similar featured microwave / hood for about $300 to $400. You might try a JVM1750DMWW by GE great micro/hood for about $300, includes one touch sensor cook capabilities,300 CFM vent fan,removable rack,option to turn the turntable on or off, 1000 watts of cooking power. Good luck !

JVM 2070 shuts off


My unit does the same thing - it will often simply power down or power down and display garbage on the control panel within a second or two of starting operation.  I have found in my case this seems related to slight obstruction preventing the exhaust hood from pivoting to the open position at the top of the unit.  Mechanical misalignment of the pivoting fan panel seems to cause a motor overdraw, or something similar, which shuts down the unit.  I've found that I can usually slide the pivoting fan panel a mm or so to the right or left, usually right (oddly), and then the panel will swivel unimpeded and the microwave will work.  As my unit has cabinets above it, I believe that over time there has been sufficient physical contact/impact with the pivoting exhaust panel to slightly deform it, affecting its ability to freely rotate down from the vertical.
