Many of these amps have a thermal fuse in the power transformer

get a tech to check for a primary connection on the transformer

There also may be fuses on the output of the transformer as well

How do I repair horn in the steering column


What is the problem with the horn. Check Fuse for Horn. Check Horn it is located under the bonnet. Near the front grill of the car. Check relay for horn most likely also located somewhere in engine compartment in a plastic box compartment with numerous relays. If horn not sounding should hear relay click when horn button pressed.
If horn is getting voltage at horn plug (positively switched horn design) then horn may need replacing.If negatively switched then horn connects to body of car when button pressed and other side of circuit has Plus 12 volts always on it.

Washer over flows


Discharge pump is clogged or not working or relay isn't working. Locate items w back off and let run if you hear relay click (it's ok) then the pump motor tries You have a clog. If relay does click or motor doesn't try that tells you what it is

Subzero 680 water dispenser working inconsistently.


This sounds like the inlet water solenoid valve is faulty. This valve is connected to the water supply line coming from your house.

Haier dishwasher stuck on auto wash


I think the flood switch has triggered which forces the pump to run continuously but does not take any other input. I am assuming it is the pump sound that you are hearing as soon as you connect power to dishwasher. The float switch is at base of dishwasher. You can press the disc visible near the filter sump. It should move up and down when you press it. If it is not moving then the spring is stuck and needs replacement. However if the disc is ok but you are still getting the problem, then you will have to check for flood switch failure. The flood switch is under the dishwasher and to access it you will have to pull the dishwasher out and lay on side. Make sure the mains power is disconnected and water inlet tap is shut.
see items 17 and 21 in this diagram.

Ac cluch does not kick in


if you press the ac button, do you hear a faint "click" inside the vehicle? someplace next to the passenger area floor there is a relay for the ac. Turn the vehicle on and press the ac switch while you are near the glovebox area and see if you hear the "click" if you hear that, your ac compressor is probably dead. If you don't hear that click. it's possible that the ac relay is dead and that's usually cheap at the auto parts store. good luck!

Ford Taurus Window won't go up


If you are hearing the clicking from the power window relay the only things left would be a break in a wire or a failed window lift motor. If this window only goes down but not up I would inspect the wiring at the door jamb for a damaged wire. If this fails to go either way I would remove the panel, insert test light into the lift motor leads (X2)and actuate the switch, if I get power then I would replace the lift motor. If you get no power in one direction - test switch.

Dryer operates; washer failed during end of spin cycle. Now washer will not fill or operate. No motor activity.


Check to see if there's good water volume coming through the hoses attached to the washing machine. If there is, check to see if the screens inside the water-inlet valve are clean. (The water-inlet valve is the device on the washing machine that the fill hoses are attached to.) If they're clean, you probably have a defective water-inlet valve. If so, you should completely replace the valve.

There's no water at all If there's no water at all, make these checks:

  • Is there water getting to the machine?


  • Is the water-volume selector switch set properly and are the control panel buttons pressed in all the way?


  • If you have a Maytag® washer, is the fuse (if there is one) in the control panel at the lid-switch bracket blown?


  • Is there a faint buzzing or humming noise coming from the water-inlet valve? (The water-inlet valve is the device on the washing machine that the fill hoses are attached to.) If you can't hear anything, the water-inlet valve may not be getting any power. If you can hear some noise and there's water present, you may need to completely replace the water-inlet valve.

Unit won't power up completely


The clicks you hear are the relay that completes the circuit for 110V AC to the main power transformer. Mine had the same problem and here's how I've gotten it to work. A lightning strike near our house caused it to fail, and I traced it to the power transformer relay activation circuit. The tuner and amp were fine. I found a bad transistor in the relay circuit, but didn't have a replacement on hand, so I soldered a jumper wire across the relay switch connections on the power transformer circuit board. This connects the 110V AC directly to the power transformer. DC Power to the amp and tuner circuits will still be controlled by the power switch, but the transformer will be supplying all the AC voltages to the main board. If there is a real problem with the circuits that load the transformer or the transformer itself, then the fuse will blow. If the fuse doesn't blow then I suspect the problem is just in the power sequencing circuit itself, that is not needed for operation other than to make the unit "Energy Star Compliant". A lot of electronic items have a transformer that is not switched, and only fused, so that the supplies are available at all times.

Hi, the relay is getting a command to shut down because there is a short somewhere in the set, if you have a volt meter you can check the "chemical fuses" to see which one(s) are open and that will tell me which circuit has the short in it. be advised these are not glass fuses so if your unfamiliar with what a chemical fuse looks like you will have to look on the power supply board for a small rectangular body device with a designation printed on the board "Fxxx". check these and let me know which ones you have failed and we can go from there, BMW Rider
