Re: Fan and cook top lights no working (samsung SMH7175WC...
We see (and repair) this
a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid in about a
our Web site, you can get details of our service, plus we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
This light failure often
occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also
affect the exhaust fan operation, too. The lights and fan can be
inoperable or stuck on too.
Feel free to contact me directly (and please remind me of your
full model number) for more information & help.

The metal base may have fused together from electrical arcing when the old bulb was removed. The entire bulb receptacle (socket) will have to replaced. If you cannot do that yourself, the cost would be excessive. Just live without the light as long as the microwave gets the job done.
I understand that you want to know how to remove the cover on your Frigidaire microwave, model# FGMV205K. There are two different covers that you are able to remove for access to two different light bulbs.
If you are trying to change the Microwave Oven Light for inside your microwave:
1)To replace light bulb, first disconnect power to your microwave oven at the circuit breaker panel or by unplugging it.
2)Remove the louver by removing the three Hood Louver Screws.
3)Push in the upper tabs and pull the louver away from your appliance.
4)Remove the light bulb and replace with a new 20 watt light bulb. DO NOT USE BULB LARGER THAN 20 WATTS.
5)Close the Oven Light Cover by carefully pushing into place. Push the louver back into place (engaging both the bottom and top tabs) and change to hood Louver Screws.
If you are trying to change the light bulbs underneath your Microwave:
1)To replace light bulbs, first disconnect power to your microwave oven at the circuit breaker panel or by unplugging it.
2)To open Light Cover, remove the screw on the light cover.
3)Replace the light bulbs with new 20 watt light bulbs. DO NOT USE BULBS LARGER THAN 20 WATTS.
4)Close the Light Cover and secure with screw removed at step 2.
If further troubleshooting is needed, I ask that you please let me know the error codes displayed on your appliance. Hope this is helpful.
Inspect the power cordUnplug
the power cord and check for voltage at the outlet. Also inspect for
damage, shorts, or burn marks that can be a possible safety hazard.
Bad door switchIf your
microwave does not work at all and you know everything is plugged in
properly and the outlet is functioning, then also check the door hooks
and the door release button. Using a volt-ohm meter on RX1, check your
terminals. When your microwave door is closed you should have a reading
of zero. Once the door is open the reading should change to infinity. If
these readings do not match up, replacement of the door switch is
Blown fusesTo determine
if your fuse has blown out, which may attribute to your microwave not
running, you need to pull the fuse out using a pair of fuse pullers. Lay
it down and using a volt-ohm meter on RX1, check both ends of the fuse
in question. If you do not get a reading of zero, then you will need to
replace the fuse.
Bad fan motorLocate the
fan and remove the leads. Again using the volt-ohm meter on RX1, check
the terminals. If an infinity reading is displayed, it means that the
fan has gone bad and requires replacement.
Light bulbIf your
microwave light bulb is not working, perhaps it has blown. The first
step is to replace the bulb and power on the microwave. If this does not
correct the issue, the next step is to check the socket and wiring to
verify if that is the problem.
Light bulb socket & main control boardIf
your microwave light bulb is not working after the installation of a
new bulb, check the light socket as well as the wiring to ensure they
are properly operating. If these sources are functioning properly, the
next step is to check for a faulty control board as a possible root
cause to your microwave light bulb malfunction.
i know this is going to make no sense . but in my samsung service cd it is in BOLD PRINT YOU MUST DISCONECT POWER BEFORE REPLACEING BULBS , OR DAMAGE TO TIMER WILL RESULT ! the first time you changed them did you disconect power ? if not , your board might be toast , $$$$$$$$$
The control board has been damaged but it can probably be repaired.
We repair this common control board problemn on a regular basis for only $39.95 nationwide.
