I have an LG RU-42PX11 plasma tv. A couple weeks ago we heard a pop and the picture went blank. I can still change channels via cable box and I have sound but no picture.

These are the part numbers for all the boards that deal with the display. Im leaning towards the sustains as well and you need to do both at the same time cause if one is bad and you replace just one, a bad one can fry the new one.

Won'Run Wash Cycle


JB, make sure the float assy. is not stuck inside the tub. On the motor harness, you have yellow-main, red-drain grey-wash and blue is the common. Check for power to the motor during the wash cycle. On this model I believe they installed a thermal cut out after series 11. I'll keep an eye peeled for any replies..Catriver.

Blower motor does not work?


Blower motor problems are a pretty common topic. This is a basic guide on how to diagnose the problem and will work for most vehicles.

The diagram is generic and loosely based on GM's setup and more specifically a Silverado. Most manufacturers have a similar setup and the only major differences would be a ground side control (instead of the switch supplying power to the resistor it would be grounding the power from the resistor if this is the case you test light would need to be connected to power to test the switch) and late model Chrysler minivans (they use a module that looks for a difference in a/c voltage from the switch)

If the blower works on high only than likely the resistor assembly is the culprit since power to the blower essentially bypasses all of the resistors and/or the resistor assembly entirely. The reason why none off the other speeds will work is that the resistor or the circuit for the speed four setting has burned out. The lower the setting the more resistance you need to drop the voltage to the blower. The first speed setting requires all four resistors to drop the voltage enough to turn the blower at its slowest speed. Speed 2 needs to turn the blower a little faster so it uses three resistors. Speed 3 uses two resistors and speed 4 uses one.

In some cases the fan will work on high and speed setting 4. The likely cause for this is the speed 3 resistor or circuit has burned out. Speed 4 still works because it doesn't use the lower speeds resistors to control the speed of the blower. If the speed 2 resistor burns out than speed 1 and 2 will not work but 3, 4 and high will continue to work. If the speed 1 resistor burns out than speeds 2, 3, 4, and high will continue to work.

This leads us to how do we know if its the resistor or the switch or the blower. If the blower works on high than we know the blower works. That leaves us with either the switch or the resistor assembly (there are many other possibilities) which can be easily tested with a test light (or a voltmeter if you choose) The first thing to do is locate the resistor assemble. They can be behind the glove box, under the dash close to the blower motor or under the hood, again usually close to the blower motor. It will typically have 5 to six wires going to it. We'll start by unplugging the connector, turning the key on and connecting your test light to ground.

1.Turn the switch to high and backprobe all the wires. Two of them should illuminate the test light. In the diagram below this would be wire E & F. If you don't have a diagram then hold the test light on one of the two wires and move the switch to another speed setting. the wire that continuously illuminates the test light regardless of the switch position will be the constant power for high blower speed and will not need to be rechecked in the following steps.

2. Turn the switch to the next lowest setting. Backprobe the remaining wires to see if one of them illuminates the test light. Repeat until you have checked all of the speed settings.

3. If the test light has illuminated a different wire for each setting then we can reasonably assume that the switch is functioning as intended and the source of the problem is the blower resistor.

If you find one or more settings (but not all the settings) on the switch that does not illuminate the test light on any wire than we can reasonably assume that the switch has failed.

There are a few other things that can cause blower motors not to work as intended. The switch or the resistor assembly are the two most common problems.

Heater blower motor quit...need to find ground for resistor


I suggest you find your fuse/ relay center check fuses and try new relay, I think the relay is 75% at fault most of the time.
Blazerk from Altima forum suggest
Back probe the blower motor Blue/Yellow circuit and tap it to ground, if that doesn't make the blower operate, the blower motor/power transistor assembly is bad. When the blower motor does operate while grounding that circuit, the climate control panel may be faulty, repeat the test from the connector at the control panel to verify the wiring is not damaged. Also, When verifying voltage, Use the power and ground wires to the blower motor. Other grounds may give you faulty readings.

Hotpoint oven bs43


you need to send the full model number,most likely you have a bad clock assy.even though your clock might work it comes with the clock and a computer board all together.i never heard of resetting a timer,i do know that if you unplug or shut down the power from the fuse box for 5 to 10 minutes sometimes resets the computer just like a regular house computer, it sounds like your loosing power and i don't think resetting anything is gonna help you,also make sure you have 240 volts going to the oven,but if the fan and light are not working and no heat it sounds like you have a bad clock assy.if it's in good shape and depending on the age you might want to call someone in to check it for you,if it is the clock assy. it might not be avalable anymore but there are companies that can rebuild the clock assy. you have.good luck with your oven.

Roper dryer res7648kq0, replaced heat element, thermal fuse, cycling thrm, thermal kit, checked outlet, circuit breaker, still not heat, will not advance on AUTO, but will on timed cycle. Now what?


Wow.
In electric dryers with an AUTO cycle; the heater runs on 220 volts, but the timer motor runs on 110 volts. There is a resistor in the system to cut down the voltage. If the resistor is bad, you will see the same symptoms as if a thermostat was bad. The timer motor will not run in the automatic cycle. You need to make sure that you test for continuity in the resistor.
I've looked at two parts diagrams for your washer and cannot find a sensor anywhere in either, so the thermostat is what tells the timer to advance once the dryer reaches a preset temperature.
The thermostat will only tell the timer to advance if the dryer reaches the proper temperature, if you have some clogging in the vents, the dryer may never reach the proper temperature, and thus not advance on the auto cycle. but i'm sure you've probably checked that. I'm baffled. Let me know how it pans out if you can. Thanks. I'm still trying to find a wiring diagram for that model.

thanks,

Mike

Air/heat not blowing from vents, can feel the heat but it's not blowing, I turn the knobs to high blow and it won't do anything, its cold outside,


if the fan does not increase speed as turned up replace resistor assembly usually in heater housing under dash.if doesn,t nave separate resistor assy.it is the fan switch

I would like to know how I can fix the heater in a 89 gmc k1500 with a 350 engine and no air. I tried a new heater motor and still not working. The Fuse is also good.

Maytag neptune front loader washer has NF error code


Does it agitate and does the door lock light come on? Theres a panel on the back you can take off via 4 screws. Here you can check the belt and watch to see if it spins or moves at all. If the door lock light comes on, and you here the door click. Than chances are your motor control board is bad. Seen this many times. Im actually replacing one tomorrow on the exact washer.I believe the part # is 22004045. Heres a diagram. If the door doesnt lock than you need either a lock assy or a new computer for it. The computer is in the top panel where the timer is. If you look at it you should see a burnt resistor. If no burnt resistor than its more likely th lock assy. Ill try and find the part # for the lock and computer, and a digram. Hope this helps. Dave www.washermd.com

I believe my heating/ac motor resistor is bad - fan doesn't work on high


Look behind the glove compartment door. Press the tabs holding it inward to let it drop out of the way.
I'm getting suspicious that the resitor block isn't to blame for these problems. May be the switch. The resistor block looks to be bullet-proof but it is a hard to test assembly.
