Question about Hotpoint JE740WY/GY Microwave Oven

1 Answer

Hotpoint microwave key pad parcially not working

Some of the keys ( 1, 2, 3, 4,) wear working and most of the buttons wear not. I was still using the microwave but today the microwave was showing PF and no buttons worked. Could the problem be in tthe control painel, or simple cleaning will fix it. The microwave has 5 years and looks and works perfectly. The only problem would be on the keypads.

The pads actually share some of the same lines inside the touch pad. There are silver oxide traces inside there. If a trace inside breaks, it depends on which trace breaks as to what pads dont work. If a trace that is common to say pads 1,3,5,7 you would lose function of those pads. 1.....2.....3.....4......5....... it is sort of set up like that inside wher eone connects to another and so on. So lets say a line between 2 and 3 breaks then you would lose pads 3, 4, 5 and any others on that same line. Will have to replace touch pad, cannot repair.

Magnatron is suspect. Need to put a voltmeter on it and see if the input (primary) side to the high-voltage transformer (big heavy iron thing in there) is getting 120Vac. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing the magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"

Sadly, we hear of this over and over.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

They may send you a replacement magnetron. GE Customer Service is here.

F3 on a GE / Hotpoint microwave means you have a shorting membrane keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

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.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

Yes, it's probably a failing membrane keypad.

Since you didn't mention the model number, I have to be kind of general.

On some models, the membrane keypad has to be peeled off and a new one stuck on.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

On some models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In that case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

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.

Next, disconnect the strip as shown in the photo below, then remove the screws that hold your circuit board in the old frame.

Sounds like a replacement control panel will be required. They do fail and usually are not a serviceable part.
Call an engineer for fitting.

Several buttons on key pad of microwave are not working


Steam got into key pay. Sometimes it will dry out. Take key pad apart and try to dry with a hair dryer, not to hot, you just want to blow condensation out of it. If this does not work, key pad needs to be replaced. The problem is they cost as much as a new microwave.

KEY PAD INTERMITTENT


Dampness or moisture that gets into the membrane will cause this as well as it just wearing out over time, and the best fix is to replace the pad since the ability to work properly will be temporary at best.

I report from owner manual.

F3 means : Short circuit on key panel (your touch pad).
You get F3 error if a shorted key panel is detected for more than 60 seconds.
Solution: . Replace key panel (touch pad).

Try first unpluggign power cord for five minutes.

If you think that the problem may had been caused by water inside the keypad you can try using an hairdryer on the keypad, taking care not to melt the keypad plastic.
If that does not work, then replace the keypad.

You can buy replacements here. or Order GE Microwave Ovens Parts Here

Your Control Key Pad is a circuit with each function and button a switch. The pad on your TV Remote, and Telephone is no different. The Key Pad is failing, It will only get worse. Determine if you can replace the Touch (Key) Pad. Not the Control Circuit, just the Touch Pad. Sometimes you can get it seperate. It connects by a Flex Cable to the Control Circuit.
