hi there,

the tube that you are talking about is the water line and it runs all the way to the icemaker. not sure about the copper line and it's also not a good idea, as cooper conducts electricity and you may damage your heat exchanger or even worse your compressor. i would have a technician come and take a look at this one. the mfg. should have a water line freeze kit available to remedy this problem.

That sounds like the heater bypass tube. On the end of the tube going into the water pump is an o-ring. Pull out the tube, clean it real good, put a new o-ring on it. Clean the hole well that it goes in. Then I will put a slight amount of silicone around the o-ring. That helps it go back together and fills any imperfections.
Hope this helps you.

No reset button, there's nothing to reset in it. If you don't get heat and everything else is working that means that the magnetron tube isn't working.
The tube doesn't work because either it's defective ir it isn't powered. To check which you must open the oven and test the power to the magnetron.
Beware, if you don't know how to do that safely or you don't have a very good voltmeter then don't touch it, the very high tension inside can easily kill you.

How do i fix my whirlpool icemaker it seems that it gets stuck half way into icemaking and does not produce ice.the model is ed5hhaxv002 it is very frustrating i havce tried a blow dryer to heat the r


Your rubber tube is most likely not freezing up and therefore does not need to be heated but only you would know for certain. My experience with ice makes spans several different models but I've found the most common problem for me with no ice being produced is when the bar that shuts of the icemaker gets stuck in the up position because - ice cubes have frozen into a big clump, Ice cubes have jammed the bar by sticking between the ice tray and the bar, or the gear inside that rotates the ice cube tray is stripped in that area because of previous jams and needs to be replaced.

Fridge freezer, water inlet pipe keeps warming up


The home icemaker's predecessor was the plastic ice tray. It's fairly obvious how this device works: You pour water into a mold, leave it in the freezer until it turns to a solid and then extract the ice cubes. An icemaker does exactly the same thing, but the process of pouring water and extracting cubes is fully automated. A home icemaker is an ice-cube assembly line.

Most icemakers use an electric motor, an electrically operated water valve and an electrical heating unit. To provide power to all these elements, you have to hook the icemaker up to the electrical circuit powering your refigerator. You also have to hook the icemaker up to the plumbing line in your house, to provide fresh water for the ice cubes. The power line and the water-intake tube both run through a hole in the back of the freezer.

When everything is hooked up, the icemaker begins its cycle. The cycle is usually controlled by a simple electrical circuit and a series of switches.

At the beginning of the cycle, a timed switch in the circuit briefly sends current to a solenoid water valve. In most designs, the water valve is actually positioned behind the refrigerator, but it is connected to the central circuit via electrical wires. When the circuit sends current down these wires, the charge moves a solenoid (a type of electromagnet), which opens the valve.

The valve is only open for about seven seconds; it lets in just enough water to fill the ice mold. The ice mold is a plastic well, with several connected cavities. Typically, these cavities have a curved, half-circle shape. Each of the cavity walls has a small notch in it so each ice cube will be attached to the cube next to it.

Once the mold is filled, the machine waits for the water in the mold to freeze. The cooling unit in the refrigerator does the actual work of freezing the water, not the icemaker itself. The icemaker has a built-in thermostat, which monitors the temperature level of the water in the molds. When the temperature dips to a particular level -- say, 9 degrees Fahrenheit (-13 degrees Celsius) -- the thermostat closes a switch in the electrical circuit.

Closing this switch lets electrical current flow through a heating coil underneath the icemaker. As the coil heats up, it warms the bottom of the ice mold, loosening the ice cubes from the mold surface.

The electrical circuit then activates the icemaker's motor. The motor spins a gear, which rotates another gear attached to a long plastic shaft. The shaft has a series of ejector blades extending out from it. As the blades revolve, they scoop the ice cubes up and out of the mold, pushing them to the front of the icemaker. Since the cubes are connected to one another, they move as a single unit.

At the front of the icemaker, there are plastic notches in the housing that match up with the ejector blades. The blades pass through these notches, and the cubes are pushed out to a collection bin underneath the icemaker.

The revolving shaft has a notched plastic cam at its base. Just before the cubes are pushed out of the icemaker, the cam catches hold of the shut-off arm, lifting it up. After the cubes are ejected, the arm falls down again. When the arm reaches its lowest resting position, it throws a switch in the circuit, which activates the water valve to begin another cycle. If the arm can't reach its lowest position, because there are stacked-up ice cubes in the way, the cycle is interrupted. This keeps the icemaker from filling your entire freezer with ice; it will only make more cubes when there is room in the collection bin.

This system is effective for making ice at home, but it doesn't produce enough ice for commercial purposes, such as restaurants and self-service hotel ice machines. In the next section, we'll look at a larger, more powerful icemaker design.

There are any number of ways to configure a large, free-standing icemaker -- all you need is a refrigeration system, a water supply and some way of collecting the ice that forms.

One of the simplest professional systems uses a large metal ice-cube tray, positioned vertically.

In this system, the metal ice tray is connected to a set of coiled heat-exchanging pipes like the ones on the back of your refrigerator. A compressor drives a stream of refrigerant fluid in a continuous cycle of condensation and expansion. Basically, the compressor forces refrigerant through a narrow tube (called the condenser) to condense it, and then releases it into a wider tube (called the evaporator), where it can expand.

Compressing the refrigerant raises its pressure, which increases its temperature. As the refrigerant passes through the narrow condenser coils, it loses heat to the cooler air outside, and it condenses into a liquid. When the compressed fluid passes through the expansion valve, it evaporates -- it expands to become a gas. This evaporation process draws in heat energy from the metal pipes and the air around the refrigerant. This cools the pipes and the attached metal ice tray.

The icemaker has a water pump, which draws water from a collection sump and pours it over the chilled ice tray. As the water flows over the tray, it gradually freezes, building up ice cubes in the well of the tray. When you freeze water layer by layer this way, it forms clear ice. When you freeze it all at once, as in the home icemaker, you get cloudy ice.

After a set amount of time, the icemaker triggers a solenoid valve connected to the heat-exchanging coils. Switching this valve changes the path of the refrigerant. The compressor stops forcing the heated gas from the compressor into the narrow condenser; instead, it forces the gas into a wide bypass tube. The hot gas is cycled back to the evaporator without condensing. When you force this hot gas through the evaporator pipes, the pipes and the ice tray heat up rapidly, which loosens the ice cubes.

Typically, the individual cube cavities are slanted so the loosened ice will slide out on their own, into a collection bin below. Some systems have a cylinder piston that gives the tray a little shove, knocking the cubes loose.

This sort of system is popular in restaurants and hotels because it makes ice cubes with a standard shape and size. Other businesses, such as grocery stores and scientific research firms, need smaller ice flakes for packing perishable items. We'll look at flake icemakers next.

In the last section, we looked at a standard cube icemaker design. Flake icemakers work on the same basic principle as cube icemakers, but they have an additional component: the ice crusher. You can see how a typical flake system works in the diagram below.

Like the cube icemaker design we examined in the last section, this machine uses a set of heat-exchanging coils and a stream of water to build up a layer of ice. But in this system, the coils are positioned inside a large metal cylinder. Water passes through the cylinder, as well as around its outer edges. The passing water gradually builds up a large column of ice surrounding the cylinder from the inside and outside.

As with a cube icemaker, a solenoid valve releases hot gas into the cooling pipes after a set length of time. This loosens the ice column so it falls into the ice crusher below. The ice crusher breaks the ice cylinder into small pieces, which pass on to a collection bin.

The size of the ice bits depends on the crusher mechanism. Some crushers grind the ice into fine flakes, while other crushers produce larger, irregularly shaped ice chunks.

There are many variations on these designs, but the basic idea in all of them is the same. A refrigeration system builds up a layer of ice, and a harvesting system ejects the ice into a collection bin. At the most basic level, this is all there is to any icemaker.

It heats up but no steam


i just fixed mine tonight. it was heating but not releasing steam. i took apart the mop, not the head and found that the tube connecting to the heating element popped off....the spring inside the tube was also haning out. i found the metal clamp that was holding it randomly in there as well. i pushed the spring back in the tube and then pushed the clamped back onto the tubing, then pushed the tubing back onto the heating element then slid the clamp down over the tubing and the heating element and now my shark works great again!!

Hi,I just bought a Roland FS 1 footswitch.I have a Laney AOR 100 tube amp which takes a Laney FS 1 footswitch.I was hoping the Roland would work with my Laney but it doenst.I bought the Roland used as well...


OFTEN Roland has the opposite sense of normally closed contacts versus normally open. Test the switch with any continuity tester or an ohmmeter to see that the contacts work and come out to the switch. ALSO some amps require a TRS type connection (three wire plug) and others do not. From the schematic it appears that the Laney may REQUIRE a normally closed contact. There is also a pull switch involved that you MAY have to change the state of for operation of the pedal.

Here is the scheamtic for your amp:

Ice maker will not fill with water


Water might be frozen in the tube that fills the ice tray. Check the tube and if it's frozen shut, use a hair dryer to heat it until the ice piece melts out. Your icemaker should work after the fridge has been closed for 24 hours to cool back down.

Icemaker water overflows into freezer


the condensate tube is run incorrectly on this model and goes uphill into the area above the refrigerator where there is a condensate pan. This will plug and back up and cause this problem. I have fixed ours several times but it always came back. The last time I bought a new clear plastic tube and reran the condensate out the back of the refrigerator and down through my floor. It's all downhill now and seems to have fixed the problem.

Toshiba televison picture keeps going yellow


Sounds like the blue is disappearing from your picture. A common cause of this is bad solder connections which can cause the blue signal to be lost at several places. It could also be due to picture tube failure. Sadly, I'm leaning toward tube failure because of your description. Bad solder connections usually take some time to start acting up after you turn on the set, but you say this happens every time within a few seconds. This is typical of a picture tube failure where an internal connection is okay until the tube heats up, and that takes only a short time. A service shop could check the set to make a firm diagnosis, but if the tube is the culprit you should replace the TV. It's not economical to consider tube replacement.
