SOURCE: Unit not getting power

These machines seem prone to having a bad magnetron. Look for a circuit breaker near the power cord entry point. If tripped, reset and try to heat a cup of water. If it makes a loud buzz and then pops the breaker again, the consensus view is a bad magnetron. This is one repair that is recommended to send out. (~$150). You need to evaluate the probable cost vs a new machine.

SOURCE: Hotpoint rvm1435 microwave: seemingly no power

In addition to the fuse, the safety devices which will render the oven dead during a fault condition are the bottom TCO and the cavity TCO.

The TCOs (thermal cutouts) have thick black wires connected to them, and they should both read "closed" or zero ohms when you do a continuity check on them.

Do not confuse the hood TCO, which has thinner red and blue wires connected to it and which are supposed to normally read "open" or infinity. If the hood TCO were bad, the hood vent exhaust fan would run all the time.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

No power at unit. Power to plug


Jim, Take the screws out that hold the cover on your unit and then take the cover off. Find where your cord goes into the machine and follow the black wire from the cord, it normally should go to a small circuit board and your fuse is usually mounted on that circuit board. It will be a 15 amp fuse and you usually can get one of those at most appliance parts stores. If there is not a circuit board the black wire may go directly to an in-line fuse holder. Hope this helps.

My hotpoint oven lost all power while cooking


Might be a fuse inside, or the unit may have died. Contact the manufacturer and keep the unit unplugged.

No power. outlet is good, microwave plugged in. no lights, no power, nothing. does this unit have a power supply that might have gone bad?


Hello,

the problem of this unit is power related.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.

If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.

When electric current comes from the power outlet into the cooker, it goes straight into the power supply board which then circulates the current into the unit. So if the cooker doesn't power on, the first thing is to make sure there is power entering into the machine.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

If any machine or electronics device doesn't power on, it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

SET TIMER FOR 20 MINUTES FOR BAKED POTATOE.. CAME BACK AND FOUND POTATOES CHARCOALED. SMOKE AND SINGED INSIDE. MICROWAVE WILL NOT COME ON. CHECKED CIRCUIT BREAKER. POWER TO UNIT.


That was a very long duration to have set for potatoes. It would have made the magnetron burnt by exeeding the limit and findinf there was no conductive medium by moisture , it has ended up burning the magnetron.
First of all clean up the inside and clean up the point of the magnetron beam.Now confirm on the inside to be totally dry.
Disconnect power and check inside for break of fuse to the magnetron.If the microwave does not heat on testing with a cup of water , then it is possible that the magnetron is cooked.
Confirm the cost for the unit to decide on replacement.
Hope this helps.

I would suspect the fuse or magnetron thermostat.

Ok , I replaced the fuse checked all connections and checked plug for power ! Still my lg lmv1630st will not show any power at all . What gives?


by replacing the fuse you meant the house circuit fuse or the microwaves internal fuse? and by conncetions your talking the internal wiring inside the case of the unit or wiring from the plug? if not its your 15 or 20 amp ceramic fuse inside the unit,if thats blown replace,but chk h.v.diode,v.v. cap,triac,control board, mis-adjusted interlock safety door switch,and lastly the mag could be defective

Has power to unit but nothing works, ie. oven, clock, timers, etc


If you don't see any light in the display or from the light bulb inside it you probably need to replace the fuse inside the microwave, it should be by the place where the cord goes in the microwave.

Sharp R1420B Totally dead. Power to unit is ok.


Most of these have internal line fuses inside of the casing. Once you remove the housing that covers the top and sides, follow the wires from the cord and they should lead you to the fuse. They are usually on the front rh side looking at it from the front. Be careful, even though unplugged, this unit still stores alot of electriacal energy in the capacitor.

Hotpoint Microwave Mod. # RVM1435WD001 Stopped warming


I just had the same problem with my over the range microwave in my RV. I took the unit out, took the cover off to expose the inside and found that the magnatron was fried (where the wires plug into the magnatron, the plastic shield was melted). I ordered a new one from repairclinic.com for 126.00. It was very easy to install, only one screw held it in.
