It could be off on a low pressure switch. You need to check if you have 24 volts to the outdoor unit at the contactor coil. If the contactor is not working the outdoor unit will get no high voltage to the compressor or fan. It could also be that the capacitor for the fan and compressor is blown.

How can a toggle switch be added to a light cord?

Think this one through. There are a few different switch options as far as what can be added to the line cord of a light. A toggle isn't one of them. The in-line switch comes in a few different flavors. The rotary switch is arguably the most common. It's got that little wheel. There is a rocker switch, too. It's pretty close to a toggle in action, so you should look at this one closely. There is also a larger-bodied dimmer switch that can be put in the line cord (but it's for incandescent and not for fluorescent lights). This bad boy has a wheel on it that can be rolled from a point where it "clicks" and turns the light on, and then allows the gradual brightening of the lamp from barely visible to a "full on" position. The big name manufacturer Leviton makes all these switches, but so do other companies. All are designed and engineered specifically for use in a line cord for a lamp. And that's the value of the products. You don't have to figure anything out. Were you planning on installing your toggle switch in a little box to isolate and protect the wire lugs? Or were you just gonna wrap a bunch of black electrical tape around the whole thing? (The former is a pain, and the latter is not advised.) Make a friend in the electrical department of your local hardware store or home center. Pick the right in-line switch and then install it correctly and safely.


What causes a capacitor to blow?

Capacitors can fail for a few reasons, and sometimes the do "blow". Capacitors have voltage limitations which, if they are exceeded may cause internal arcing or flashover. Once initiated, arcing can cause sudden heating and if the circuit supports high enough energy the capacitor can be damaged and may actually come apart. For polarized capacitors, reversing the polarity may even result in catastrophic failure at normal voltage levels. Another reason capacitors fail is as a result of high current. If a capacitor is subjected to high frequency currents of sufficient magnitude internal heating can result and once again damage will result. With enough energy it may come apart. One last way capacitors may be damaged is through sudden discharge. Generally high voltage ceramic capacitors may be charged to high energy levels. With a sudden discharge ceramic capacitors can respond with a piezoelectric effect and the ceramic may actually shatter.

Why would a refrigerator keep tripping the breaker?

Earth leakage or problem with the switching when the condenser clicks on is often the problem. This often causes an electric 'arc' which grounds to Earth, causing the breaker to switch. It often happens when fridges & freezers get ol

Why would Window AC unit and TV go out checked breakers all ok switched breaker on and off still nothing overhead light in room is working any idea?

If A/C unit and TV are on the same circuit it sounds like a breaker trip. If it is not evident which breaker tripped move all of the breakers off one at a time. Move completely to the off position. You should come across one that clicks when moved to the off position. This is the tripped breaker.


How is the game Bubble Breaker usually played?

Bubble Breaker is played by clicking pairs of similarly colored bubbles in a play-field of multi-colored bubbles. When the player clicks two adjoining bubbles of the same color, they are eliminated from the field and more bubbles take their place. The game ends when there are no more possible moves.

What is PAR in red remover?

its how many clicks you have to do it in. so if it says par=2, it means you have to do it in 2 clicks or less. but don't let the clicks get you confused with the par. clicks is how many clicks you did it in last time and par is how many you actually have to do it in. you only pass when the clicks is equal to the par.


Why does the fuse box in my house make a clicking noise when the heater clicks on?

The clicking noise you are hearing could be the heater is overloading the breaker and it is on the verge of tripping This could be caused by the heater being to large for the circuit. Check the amperage rating on the heater and the rating on the breaker It also cold be the circuit breaker is going bad and needs to be replaced by a qualified electrician These are 2 possible answers you also could have a bad (loose) electrical connection some where in the circuit
