Clearing "filt" messages from Samsung commercial microwave oven displays.

Filter reset instructions for Samsung and Buffalo commercial microwave ovens.


When "Filt” shows in the display it does not indicate a fault. It is just a preprogrammed reminder to clean the air filter located underneath the oven door.
The filter should be removed and cleaned in warm soapy water or in a dishwasher, dried and then refitted.
The oven needs to be ‘told’ that the filter has been cleaned and the reminder reset using the following procedure.
Press and hold the programme lock button (the small circle below the P key) and pad number 3 together.
After 2-3 seconds the number of hours for the timed reminder is displayed.
Enter the number of hours you want before the next reminder.
Press and hold the program lock and pad number three together again until the oven bleeps once.
Press the cancel button to clear the hours message from the display.

Do you ever check your plugs ?

Image

Do you ever look at the plugs on your appliances. Many electrical appliances around the home will have been supplied with a moulded plug top which is virtually maintenance free, but there are still of home fitted plug tops around. We see a large percentage of microwaves that come into our workshop with after market plugs fitted. Please check from time to time. especially if its a plug that gets used or moved around a lot as appliances such as irons are taken from or put into cupboards. Check that the plug top itself isn't broken. Often parts of it will break off as the material is quite brittle.ImageI wouldn't expect anyone to take a plug apart for a routine check (that's our job. when a microwave comes in for repair we always check the plug top and cable for signs of damage), but if the lead feels or looks  loose, then you should check inside. The screws can come loose or may have been fitted too loosely during fitting.

 

One of our technicians during a routine repair just recently checked inside to see several of the wire securing screws actually missing - not even inside the plug top.ImageI could mention about how to wire a plug but its almost a topic in itself. For now check the first picture by the title of this post. That's pretty much what it should look like, at least what colour wires go where. Finally, If the fuse goes and you need to change it, please make sure you change it for the correct rating, replace it with the same colour fuse. Usually 13 amps for most kitchen appliances. If it blows again you need some expert help to check the appliance as there is probably a fault.

I can see through the door, how is it these microwaves can't get out?

You can see through the door because the holes in the metal mesh are small enough for the light"waves" to pass through, but the microwaves are too big to fit through the holes (I know this sounds odd because we are talking about something we can't see!).

Just imagine that you have got a wire mesh, with holes about the size of a pea in it, along comes some light (imagine it as a marble) that's 1/10th the size of the hole--it will drop through a hole in the mesh, now along comes the microwave which is a bigger glass marble, about the size of a 2 pence coin, it's far too big so it just bounces off the mesh, it can't get through.

This is just what happens with light and microwaves in the microwave. To the microwaves the mesh looks just like a solid metal screen; and they bounce off just like radar waves bouncing off of a ship or aeroplane, but to the light the screen is not very substantial and the light just streams through.

Panasonic Bread Machine Mounting Shaft

[caption id="attachment_695" align="aligncenter" width="300"]Panasonic breadmaker mounting shaft kit Panasonic breadmaker mounting shaft kit[/caption]

We have had a few instances of customers purchasing either mounting shafts or mounting shaft kit (kit.005) because the kneading blade has been loose on the shaft only to find that the new parts are exactly the same. The blade normally sits quite loosely on the shaft. It is designed with enough tolerance to allow for the non stick coating to be applied during manufacture. it doesn't matter that it is loose because it is driven positively by the flat portions. The blade only turns in one direction so there is little chance for excessive wear. Even being loose we or Panasonic UK have never heard of a blade coming off of the shaft during operation. To that end we advise that as long as everything is working ok not be concerned that it looks to be loose. The main reason to change the mounting shaft is when the seal fails and allows mixture to seep through into the pan of if the bearing fails and it either seizes or makes excessive noise during operation.

Heating plates in the microwave

Just recently I have had a few phone calls from customers who have damaged their microwave by using it to warm plates.

In a nutshell, don't use your microwave to warm plates.

Very briefly, microwave ovens work by emitting microwave energy into the oven. This in turn agitates water molecules in the food or drink in the oven. The friction of those molecules creates heat and - hey presto - hot food is the result.

Plates have very few if any water molecules in or on them, therefore if you only put plates in the oven, the microwaves will bounce around the oven looking for something to absorb them. Eventually, something else in the oven will get warm. it might be the plastic roller ring, the mica waveguide cover or any plastic parts of the inner door.

It may be that you have been doing this for a while with no problem, this could be due to a number of factors such as the quality or type of plate. Some cookware may have moisture inside which more readily absorbs the microwaves, whereas some cookware will be completely invisible to microwaves (this wont get warm at all).

On a few occasions problems have occurred where the microwave is a replacement microwave and is either much more powerful than the last or through its design is less tolerant of microwave energy bouncing around inside.

Either way, if the microwave is used for heating plates eventually some damage will occur. The plates could break. The microwave oven might even end up cooking itself ultimately which will of course result in costly repairs or replacement.

If you really want to use your microwave to heat plates try putting a bowl of water on top of the plates so that most of the energy will be absorbed or if your microwave is a combi oven warm the plates with the grill of convection instead. It may take 5 minutes instead of 1 minute but wont affect the microwave in any way.
