It can be obtained by any tv spare parts shop. of course you will have to show him the size of membrane and switch assembly. no special instructions. any skilled person can do it knowing about it.

Need to install membrane switch model number smh9151s


This is actually a simple DIY job. The service manual is at my site here.

You simply move your circuit board into a new control panel frame assembly, which comes with a new keypad already attached.
For model SMH9151S, it is part number DE94-01806K ("Assy Control PANEL") and you can order it from the Pros here for about $42.

If it is not in stock when you order, they can have it to you in just a few days.

You can also find helpful exploded view diagrams and order other parts via that link.

There's a video here showing how to remove a typical over the range control panel assembly in under 5 minutes. If you have trouble, slide the hood vent grille to the left about 1/4", then then pull it forward. Then you unplug the keypad (as per the photo below) and move your circuit board into the new frame. Be careful, since the display is made of glass.

Some connectors on the relays have a lock:

The display is showing the letters SE. What does this mean?


Unless there is moisture or grease on the control circuit board, "SE" error means you have a shorted membrane keypad.

The solution is actually a pretty simple DIY job - to replace the control panel frame assembly - which comes with a new keypad already installed.

If I had your full model number from the tag on the oven I could likely give you step by step instructions with the part number you need.

You can find links to helpful exploded view diagrams and part ordering help here, where you can also e-mail me directly.

I recommend that you bookmark that link to your favorites.

Samsung microwave SMH9151W displays code -SE-


"SE" means you have a defective membrane keypad. There are two ways to fix this:

1. Replace the membrane keypad. If you (or someone you know) might want to replace it yourself, there is a handy guide with pictures showing you what's typically involved. It is part number DE34-00304G.

2. Replace the control panel frame assembly (part number DE94-01806J) which comes with a new keypad already installed. Details are below.

There is a a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Some connectors have a lock.

Then simply move your circuit board into the new frame.
You should first contact these parts suppliers to see which if either parts are in stock or still actually available:

Sears Parts Direct
Encompass parts (or you can call them toll-free at 866-779-5835)
The Pros here

Again the parts are:

DE34-00304G membrane keypad switch
DE94-01806J control panel assembly

How do i fix the se on a micro wave


"SE" means you have a defective membrane keypad.

With your full model number, I could have given you detailed instructions and parts numbers.

But without that, I'll have to just be generic.

If your model's membrane keypad is available as a separate part, that's usually the cheapest but most involved way to fix it.

Here is a handy guide with pictures showing you what's typically involved.

If it's not available separately, then you can replace either the control panel frame assembly, which comes with a new keypad on it, or the entire control box / controller assembly.

There is a a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

I have a Saniplus in my bathroom its connected to a sink, toilet and shower. The thing is when it is used its fine but after the pump stays running, until you tap the machine in the middle on the right,...


Your saniflo has a membrane that covers the electric and switch, it is probably starting to get covered in limescale, have you tried descaling the unit, you can get descaler from saniflo and the instructions are on the bottle, its very easy to do, there are otherb cheaper makes of descaler but as far as I know saniflo descaler is the only one with the instructions on the bottle.

There are other things it could be like a faulty switch or heavy/hardened lime scale on the same membrane mentioned above or the membrane could of be deformed and lost it's shape causing the problem, but all of those problems would need a engineer and maybe even parts, so try decaling first

Megaworks 550d doesn't switch on


Step 1:

i had same problem with my magaworks 5.1 thx550.
i have tried to find solution in web but it was only one which voltage sense resistor 2Mohm track in PCboard was damaged.
after check PCboard in my megaworks thx 550 i found that tracks are quite well and voltage sense resistor is well too.

Step 2:

REPAIRING PROCEDUREin below items there are repairing procedures that i did with my THX550.to access to BCboards it is required to remove electronic boards from woofer case.
1- remove cover of woofer.2- remove woofer speaker from case by cutting and marking connected wires.
3- remove all Philips screws around cover and remove electronic parts smoothly, care about glues around power cord.4- remove and disconnect power supply board from other parts.


3_12_2013_7_45_42_am.jpg5- replaced switcher TOP234Y and capacitors C102, C206, C205 and D10 as below photos.3_12_2013_8_08_28_am.jpg6 check all of related tracks in repairing area.3_12_2013_8_10_00_am.jpg


3_12_2013_8_48_15_am.gif7- now it is time to re assemble electronic parts very carefully and prepare for test. it is better to use isolated transformer and put a lamp in serial to protect PCboard against short circuit. if green LED (POWER LED) is on it means that every thing is O.K.
8- in this step all of electronic parts should return back to case and reconnect sub woofer connections.3_12_2013_9_02_39_am.jpg

Step 3:

after replacing damaged parts my THX 550 is working well maybe for next 10 years.
i hope above mentioned instruction can be useful and helpful.

SE error on Samsung SMH9151B. Where so I find the assembly part to order?


"SE" error means you have a shorted membrane keypad.

The full model number from the tag on the oven should be one of these:

SMH9151B/XAA (service manual)
SMH9151B/XAC (service manual)
SMH9151BE/XAA (service manual)

I've included the service manual link for each one for your convenience. They'll help you with disassembly and in getting part numbers.

You can order parts by entering part numbers or your full model number from the tag on the oven here.

There are three ways you can fix this, with the last probably being the best:

1. Replace the membrane keypad ("switch membrane"). The cheapest way but the hardest. If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved. It's here.

2. Replace the control panel frame assembly ("assy control panel"), which comes with a new keypad on it already. Pretty easy, not expensive.

3. Replace the entire controller ("assy control box"). Very easy, and usually not much more than option 2.

No matter which option you prefer, at our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
