My fridge keeps tripping the power

Your solution is one of two things.

First is the circuit you have plugged the refrigerator is either over its limit and the breaker is tripping because it is overloaded. In this case you will have to determine what load also share this circuit and eliminate the extra loads or move the cord to another circuit which is not overloaded. Most home circuit are wired with 14 gauge and is rated at 15 amps. When the circuit gets to 15 amp and more, the associated breaker trips to prevent overload.

Second, Your refrigerator may have a short and needs troubleshooting to find the cause. To see if it is a bad circuit try plugging into a circuit via extension cord to circuit in another room receptical. The reason I say another room, when electrical installers wire circuits, you can put several recepticles on the same circuit. If you plug your refrigerator in the same circuit you had it on before then you will get the same problem, your refrigerator tripping again. If your frig trips on a different circuit then troubleshooting the cause will normally require a tech.

Good luck and hope this helps.

1) If the OUTDOOR A/C Condensing Unit is running BUT the indoor AIR HANDLER is NOT running, the problem could be as easy as changing the RUN CAPACITOR which is usually located within very close proximity of your indoor air handler motor. Ensure the ELECTRICAL DISCONNECT SWITCH is "OFF" and change the oval run capacitor (usually a 5 microfarad capacitor). This SHOULD fix your problem.

2) If the OUTDOOR A/C Condensing Unit is NOT running BUT the indoor AIR HANDLER is running, the problem could be as easy as the outdoor unit is not receiving the required 220 Volts AC. Turn the circuit breaker for the A/C Unit OFF and then turn it back ON. Ensure the circuit breaker SNAPS when you turn it to the ON position.

3) If the previous two steps to not apply or do not work, go to the paperwork supplied with the Thermostat. Almost every manufacturer provided a TROUBLESHOOTING GUIDE within their literature. Follow those steps. If their TROUBLESHOOTING GUIDE does NOT fix your problem, they should have a TOLL-FREE TELEPHONE NUMBER provided to contact their TECHNICAL EXPERTS with your problem(s). Call them and ask them what could be causing the problem.

1991 Nissan maxima burnt fuseable link

I recommend replacing fusible links with either a fuse of equivalent value (using a standard accessory fuse holder), or with a self-resetting breaker of equivalent value. If the replacement fuse or breaker also blow, you have a problem with the circuit that needs to be corrected (which will require basic troubleshooting).

You need to trace out the circuit. Find out which receptacles,
and switches are not working. Starting at the panel, following
the branch circuit that doesn't work and check all the wiring connections. Make sure the power is off before you check these
connections for safety sake. NO SHORTCUTS!

My power windows will not work in my 1999 chevy venture someone told me to check the fuses i need a fuse box diagram please

Hi, there is no fuse, but there is a 30 amp circuit breaker in the instrument panel fuse box. I don't have a diagram, but there are only a couple of circuit breakers there. The breakers are supposed to be automatic. If the circuit breaker is thrown, you probably have a short. Use a 12 volt test light on both sides of the breaker to see if it's thrown. If both sides are hot, the breaker is still closed, and the problem is a broken wire or switch. If the breaker is open, you have a short in the switch or a grounded power wire. Either way, this will require troubleshooting. If you have a multimeter and would like to try troubleshooting yourself, I can provide some steps. Just let me know, and thanks for using FixYa.

Where is the reset button on an Amana ASZ14 unit?

I don't think the Amana ASZ14 Heat Pump has a reset switch, but you can still reset it by resetting the power (when it's not running... turn your thermostat OFF first).

To reset the power, locate your circuit breaker box. There should be a double-breaker for the Heat Pump and another double-breaker for the Air Handler. Turn them both off for at least 2-3 minutes. Then flip them back on and turn your thermostat back ON.

You're thermostat may also have a RESET button that you can push. I have to reset mine every time I change the batteries in it.

Is there another breaker i can use instead of challenger breaker less expensive

A Challenger 20 Amp single pole breaker shouldn't be priced much different than any other brand of breaker if you buy them online and not at Home Depot. That is if it isn't the Zinsco style like these:
According to Eaton's cross reference a BR 120 will cross with a C 120. You can find the cross reference here:
Lowes shows the BR 120 at 3.47

The machine just stopped. I hooked it up on a breaker and crossed over the fuse. It worked and I could set the time. However, when I put a cupof water in it and tried to run it, it threw the breaker. Is it...

In this case, it's the wiring in the wall and not the microwave. It sounds like you have over-loaded the electrical circuit. Each electrical circuit is designed to provide only a certain amount of power at any given time. The intent of the breaker or fuse (they serve the same purpose in different ways) is to keep you from using more power than the circuit was designed to carry. Otherwise you start could fires in the wall. Microwave ovens require a large amount of power run. If you plug the microwave into a circuit that already has a number of large power-draw appliances on it (like a fridge, dishwasher, toaster, oven, coffee maker, etc.), that's probably more than the circuit was designed for. Try plugging the microwave into another circuit (one that still worked when the breaker was thrown) as see if it works. If it does, the issue is with your circuit load. If it does the same thing to your other circuit, it may have a short in its wiring that causes it to draw more power than it is intended to. In which case, it's not something that can be diagnosed over the internet.
