Other specific failure symptoms include: 1) Food not remaining at the desired temperature. 2) Fridge compressor does not cycle OFF.
If the compressor motor runs continuously in an attempt to keep the fridge cool but the cabinet is still not cool enough, you will have to find the component or failure that is restricting the cooling capacity of the fridge. Check the components in the order that they are listed below. Read the rest of this entry »
Plain and twisted candle lamps are made in 25 W, 40 W and 60 W sizes and in pearl, plain, amber and silvered colours. They are made in be (bayonet cap) and sbc (small bayonet cap) versions.
These are used for wall lights and for period pendant fittings.
These are sometimes called ’strip lights‘ and are non-fluorescent, being tungsten filament lamps. There are two versions, one type is commonly used for applications in the home, and the second type is known as architectural lamps‘. Read the rest of this entry »
The amount of light given out or produced by an electric lamp — bulb, striplight or fluorescent tube — depends on the type of lamp and its wattage. The light produced is measured in lumens and a bulb or tube of a given wattage produces an average output of so many lumens. This will continue throughout most of its life.
Equally important is the number of lumens produced for each watt consumed, so it is usual to say, when comparing types, that a bulb or tube produces so many lumens per watt. The more the lumens per watt, the higher the efficiency of the lamp. Read the rest of this entry »
Do not fit a high wattage bulb into a shade or fitting designed for bulbs of lower ratings. Some shades give the maximum wattage but if there is no indication, restrict the wattage to 60 W or preferably 40 W. Otherwise overheating may occur and the shade material either melt or ignite. Damage can also be done to the fixed wiring by transference of heat through the lamp- holders; this is particularly the case if it is a close ceiling fitting. Damage can also be done to the flex, if pendant and the flex is not of the heat-resisting type. Read the rest of this entry »
Throughout this post, references are made to meters and their use in continuity testing of individual parts of the appliances and their connecting wires. All testing and checking for ‘open’ (not allowing for current flow) or `closed’ circuit (allowing current to flow) must be carried out using a battery-powered multimeter or test meter. Testing should never be carried out on live items under any circumstances. Appliances must be disconnected from the mains supply. Read the rest of this entry »
