Unplug the fridge power cord before servicing the fridge. Move the fridge out from the wall. Use extreme care when moving the fridge, because the fridge legs can tear or damage the floor.
Using hand tools, remove the screws on all four sides of the fridge or freezer doors so that you can remove and discard the defective gasket(s). Before removing the old gasket, note carefully how the gasket is installed, because the replacement gasket has to be installed in the same position as the defective gasket that is removed. Before installing the replacement gasket, heat the rubber with a home hair dryer set on low heat. This will make the rubber more flexible,’ and easier to install on the fridge or freezer door. Install the replacement door gasket by mounting the lip of the gasket under the retainer plate. Read the rest of this entry »
Move the refrigerator out from the wall. Unplug the refrigerator power cord, and turn OFF the water supply to the icemaker.
Using hand tools, remove screws and discard the defective water supply valve. When installing a water supply valve on the water heater, install only on the cold-water side of the water heater. Read the rest of this entry »
Yes, you too can be the proud owner of a home-entertainment system and it doesn’t have to cost you a small fortune. If you have ever wondered how your mates get to have sound booming from seemingly every corner of the house when merely watching TV, we have the answer (naturally!). All you need to do is connect your TV to your video machine to your Hi-fi (these don’t have to be top of the range) after having acquired a couple of cables to make all the connecting possible.
You WILL NEED
(This will vary depending on what it is that you are connecting to what.) Read the rest of this entry »
Of more unusual interest is a rise and fall pendant enabling the height of the light, suspended by the -sheathed flex, to be adjusted as required. One application is in the dining room over the dining table. As the light unit is raised the flex winds into the rise and fall unit in the ceiling plate. Matching fixed-height pendants are also available. The rise and fall principle is a development of the old rise and fall pendant operated with a system of pulleys and ballast weights.

A basic understanding of electricity is essential, even for those who do not intend to carry out any repairs or servicing of appliances. Ignorance is no protection against your own or someone else’s errors and oversights, whether with repairs, servicing or installation.
Power is supplied to an electricity substation at a very high voltage — 400,000 volts — in three-phase form. There it is converted, via a transformer, to 230 volt single-phase for distribution to our homes. In normal circumstances, current flows from the live supply of the substation’s transformer, through the electrical appliances used in the house and back via the neutral conductor (cable) to the substation transformer’s neutral pole (a closed loop).

Capacitors used for motor starting may have metal or plastic outer casings with an insulated top with two terminals. Internally the two terminals are connected to two sheets of metal foil with an insulator between. This package of large surface area is rolled into a cylinder which fits into the shell of the capacitor. As the voltage supplied to one terminal is alternating (at 50 times per second), so does the polarity of its connected foil. An opposite movement of electrons is induced in the other foil, even though they are insulated electrically. This causes a delay in the electrical path, and this, in the case of an asynchronous induction motor, gives the outof-phase feed to the start winding. Read the rest of this entry »
Most labour-saving household appliances contain an electric motor of some description. They are the workhorse of these appliances and most of them are capable of coping with the work loads inflicted upon them. However, some motors, either through poor design or as a result of manufacturers’ cost limitations, are inadequate for the job they are required to do. Adequate or not, at some point it is almost inevitable that they will fail or simply wear out. To delay this, use the appliance with some care and attention, be aware of its limitations and carry out regular inspection and servicing. This will prevent small problems escalating into major ones
Not only do the sizes of motors vary greatly between products, so too do the ways in which they work. To diagnose faults successfully and service or repair appliances, a working knowledge of motors is essential. The following provide a basic introduction to the various types, a description of how they work, the appliances in which each may be found and their particular advantages and drawbacks. Specific problems can be found on individual appliances. Read the rest of this entry »
Aschematic diagram of the internal workings of a pod-type thermostat. This type is used in appliances that have a variable temperature control. It consists of an oil-filled pod connected to the switch by a capillary tube. When the oil in the pod is heated or cooled, it expands or contracts in the tube and operates a diaphragm. The diaphragm acts on the switchgear thus breaking the circuit and in this instance, ‘making’ the other. The cooling oil contracts, pulling the switch the opposite way — back to its original position; the process repeats if temperatures change. Read the rest of this entry »
The information given here also applies to the grills on many cookers. This is a simple way to ascertain if the control is faulty. Short circuit failures on elements may damage regulators in which case, if you are in any doubt, renew it.
The following test is for a single circuit application, that is, a single element. For double regulators, that is, a double element, the same procedure will be required on both single and double operations of the switch. From off position an anticlockwise turn will put into circuit one element (usually the inner), a clockwise turn from the off position will put into circuit both inner and outer. Check that double regulators operate independently on a half turn each. For singles, use ony a full turn. Read the rest of this entry »
These are among the most frequently used items in the home. Generally, they are very reliable, but when a problem does occur, it is usually at the most inconvenient time. Over the years, ovens and hobs have become increasingly complex with the addition of digital timers, touch controls and other refinements.
It is essential to remember that these appliances are connected directly to the mains supply and, as with any repair, cleaning or service, must be completely isolated. In this instance, the main double-pole isolation switch for the appliance must be switched off and also the fuse for the cooker/hob circuit removed from the main distribution board. If an MCB is fitted in place of a fuse, ensure it is in the off position. Do not proceed with any repair or service if both these requirements are not met and also make sure you advise others who may use the switch of your intentions. Read the rest of this entry »
