    Hi squirrel

    Can you tell me a bit more about what is happening when it is overheating, what circumstances cause it to over heat, how often it does it, what levels you are running it at. Cheers

. Some models the fan only comes on when higher levels are employed, this generally to limit the fan noise from becoming background noise imposing on your listening pleasure. Who wants to here a fan going in quiet passages. The fan may well be faulty also. You will need to check to see that it is operating, and also not clogged up with dust (or cat hair is another common one)

I forgot to ask you what model the amp is, as some of the Technics range run rather hot due to class A output stages. But having said that, it should not be going into protection mode. It is highly likely that you have cracked/heat stressed solder joints about the output and or power regulator stages in the amp. The fact that it runs ok, then shuts down would point to this. The same dry solder joints could be causing the amp to overheat also, exacerbating the problem. Fault producing excessive heating of the output stages , that heat stresses stages causing more problems and the the ultimate killer of transistorised output stages, thermal runaway.

If you are able to solder well, I can talk you through resoldering the output stages, although it is really just that. resoldering anything that looks suspect. If you don't feel confident to do this yourself,a repair shop could do the work for you at a modest fee. Expect to pay for 1-1.5 hours of work to strip, resolder and soak test the amp. If the fan has failed, then add the cost of that too, as i can predict to you that if it has been running hot, then there WILL be some resoldering required anyway as preventative maintenance, allowing the tech to put a warranty on the repairs for you with confidence.

On what overload amps wil a 60amp main breaker trip

Breakers are not fast-acting.
Generally they will let heat on the wire build up slowly that can slightly exceed the actual 60 amp rating.
But amp draw exceeding 60 amps cannot last long before it will trip... each event can be different with no exact answer available.
Also if the breaker is worn out or loose on the busbar, it can trip before amp rating is reached.
Use 6 gauge wire with 60 amp breaker

You need to check the current rating of your heat strips. If it is more than 60 amps then you need a bigger breaker. If 60 amps or less then your heat strips are going bad. Also make sure your fan turns smoothly without any wobble.

Breaker trips after bout 5 minutes

Breakers trip because of heat.
When heat from wire exceeds breaker rating, it trips.
Something is causing heat on the wire, wire is too small for the amp draw, there is short circuit, or breaker is bad.
Replace breaker and/or test wire.

Put amp-meter on wire and read amp draw through wire.
Amps cause heat. That's why high voltage lines from power station are high-volt-low-amp so there is no heat loss with long distance transmission, until transformer at home converts electricity to lower volts and high working amps with enough power to run electrical devices.
Same is true for AC and DC circuits.
If amp reading on wire exceeds rating on breaker for length of time, then breaker will trip.
The fact that the breaker lets current (amps) to flow for a period of time before tripping is because the breaker is probably rated for slow-acting, or it takes a while for amp draw to heat the wire.

Following image shows amp-meter that clips over wire to get amp reading.

This tutorial will show you how to check your Smeg element and how to replace your Smeg cooker element.
Here are the 3 main faults to look for in your oven or cooker that is not heating
  • Your oven will not work until the clock/timer has been re-set after replacing an oven element or tripping the electrical supply. Consult your Smeg manual.
  • If your Oven is not getting hot or heating up it could be a faulty element, if the fan in the oven is running and the thermostat light is on, this will lead us to believe that the element has gone faulty. With grills the thermostat light should come on there should be heat, if not then this could be the grill element or the thermostat.
  • When you turn the oven on, the household electrical supply trips on the Rcd (this is the earth trip in the fuse board sometimes called the breaker tripping) your fan oven element has gone to earth and needs replacing.

Powerstar 115 tankless tripping reset ontop of #2 heat chamber #1 does not get overly warm mainly because of incoming water temp. but #2 seems to be heating after water flow stops to hot to touch and...

I don't have specific suggestion for tankless tripping breaker or if that is a circuit breaker problem or a tankless problem.

1) Move wires to another same-size breaker and see if problem persists.

2) Compare amp draw on tankless label with wire size and breaker size amp rating.
For example 30 amp breaker using 10ga wire is rated for 80% of listed amps or 24 amps.

3) If you are drawing full 30 amps, then 30 amp breaker is getting hot. Breaker trips with heat. Older breakers can trip more easily.

4) Before calling service technician, open following link for Bosch troubleshooting steps.

5) Be sure to read manual for yearly maintenance requirements.

6) Add a tempering tank for incoming cold water problem.

7) All gas tankless brands can be repaired by homeowner for $330.

Kenmore elite dryer runs for about 3 min. then trips the breakers

The circuit breaker may be tripping because of a fault with the dryer or it may be a fault with the circuit breaker being weak.

From the description you give the circuit breakers trip frequently.

I'd suggest you first try selecting the no heat air fluff cycle and run it to see if the breaker trips. If the circuit breaker doesn't trip in air fluff then there is likely a short in the heating element.

With a clamp-on amp meter you can read the amp draw of the dryer when it is heating. With the motor and element both working you would see approximately 25-26 amperes being drawn. The breaker is rated at 30 amps. If the breaker trips and only 26 amps are being drawn then the breaker is the problem.

Try the air fluff cycle first and see if the breaker will trip. Then with additional details I may be able to help you further.
