GE phone 29490GE1

I have a couple of these which have suffered a lightning surge and its getting a bit expensive to keep buying new ones. They still function but not fully. I need a circuit diagram. Can you help?
Would be nice to send it to you for repair but I live in South Africa which makes it a bit difficult.
PS
The local GE agent is not interested.

Thanks

SOURCE: My RV unit got a power surge and the microwave looks dead.

Yes they have fuses, I am positive it's your fuse, take all 5 screw's off and you'll see it at the back on the right hand side were the ac cord goes in.

I doubt you'll be able to find a service manual for this. I would take it (if it means a lot to you) to a good repair center. They should be able to troubleshoot the problem even without a schematic.

I repair GE circuit boards, but the problem is not your circuit board.

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. The parts kit is similar to this one.

(Your model may use a different kit - this is shown for illustration purposes only).

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.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

Chances are it did not damage the control(operating) curcuits, but most likely the Telephone curcuits in the answering machine.

Surges -- How to keep them from damaging your electronic devices.

Surges give me more than half of my repair jobs,so [1] it is best to simply unplug ALL of your best devices when you expect to be away for awhile, and [2] your purchase of a surge limiter will cost you less than $30 on the net, or less than $40 at Walmart or Lowes, or Home Depot, and be sure to buy a 6' length of coaxial cable at the same time unless you have one hanging around. [They are right now probably in a closet among a whole bunch of stuff that's just barely too valuable to throw away -- stuff that your sweetie has threatened to chuck any minute now.]

Your surge limiter must be rated at 3000 joules or more, and must have at least two shiny threaded 3/8th inch projections on it to accommodate coaxial cables. The limiters are easy to hook up, but you can email to me for freebie coaching if you need to. I am at [email protected]

Lightning will jump limiters sometimes, and they get tired after 3 or 4 years so must be replaced, but thereafter they remain valuable as power strips. They are far far from being perfectly protective because fragments of lightning strikes jump them and damage them, but they are the best devices that low cost technology has been able to bring to us to date.

[A 'back-up' power supply containing a battery and isolation transformer will be more protective but costs 3 to 6 times as much. You may wish to get more details about them from me, but they should only be considered for VERY expensive or very precious devices.]

Hope this helps.

After a lightning storm my Whirlpool refrigerator keeps tripping the breaker on what ever outlet I plug it into. Could it be the3n1 relay, overload, start capacitor.

Guess your refrigeratos suffered an electric surge. Might have any kind of trouble, strating form some burn's out cable to whole electric system damaged.. If you don't have the electric knowledge, for sure you should call a repair service.
For future, you should use a surge protector fpr refrigerators

It sounds as though your phone has been hit by a power surge or lightning. Try the phone at another location and try another phone at this location to make sure there are no problems with the line. I would almost bet you will find that another phone will work but this phone will not work at another location. Phones are very susceptible to a power surge and to a lightning strike. If another phone works at this location then just buy another phone. It will be cheaper than having this one repaired. Phones are cheap but repairs are not. Merry Christmas to you and your family.

Surge at low rpm

Is it brand new? If so it's pretty normal. The bikes don't like running smoothly below 2k at all. As it breaks in it will get a bit better but it's difficult to not jerk it around at low RPM and slow speeds. Best bet is to keep the RPM at 2200+. Also if it is new when you get to the 1k TPS reset it should help as well.,,,

No dial tone

Try the telephone cord from your cordless to another known working phone. I have had these cords go defective.

If the phone is really defective, it is possible that the input circuits that connect to the tele line are damaged. Common causes are voltage surges in the line or surges from lightning. Normaly these phone has protection, but this is not always absolute or fully dependable.

There are many other things that can fail in a phone to cause no sound.

If the phone is defective and it is under warranty, it would pay to have it fixed. If it is not under warranty, it would probably pay to buy a new one.
