I have the same problem.
I disassembled the bottom of the coffee maker, and unscrewed
the bracket holding the circuit card.
I cut the input power and ground wires from the plug to the card, and detached its modular wire for the heating element.
I removed the card (to take to lab for further debugging).
Then I bought some .25 inch modular tab connectors at the hardware store and attached one to the power wire formerly going to the circuit card. I attached this to the heating element.
I covered the spare ground wire with electric tape.
Now I have a coffee maker which brews coffee again (except that I must pull the plug to shut it off). I must be careful not to let the
water boil away, but that is usually not a problem.
If I figure out what is wrong with the circuit card, I will update you.
It has a microprocessor, and I am not optimistic about replacing
that (with the right program in it). If it is the triac (the component
with the big block heat sink), it can be done.

What is fault E3?


E3 means that the heating element is operating when it should not be doing so. It may be caused by an older, weaker element that is taking too long to heat the water or the thermostat may be giving incorrect readings. Ensure you are using hot water to fill the machine (if tied to your faucet water supply, run the water until it is hot before starting the dishwasher). Information from the Belling manual:

If the heating element is still heating after the allowed time, then the control board will advance the programme to next step and at the end of the washing cycle the alarm buzzer will sound for 30 sec and the display will show E3.

When the control board detects that the heating element is operating during a non heating step or during the internal test the heating circuit is found to be open circuit then the alarm buzzer will sound for 30 sec and the control board will cease all functions except for the drain cycle which will run for 90 seconds and then E3 will be displayed on the control panel.

Lower oven heating element burned out on my **********0 kenmore range i replaced it but oven still won't work any idea's?


If the element you installed is good , then you do not have your voltage to the element. Thea is because there is an interrupted circuit, maybe an internal iven fuse or your oven breaker in the breaker box in the house

Dodge magnum pickup heater wont get hot


test the parts and fix it. God bless you

Test and replace a heating element:
  1. Turn off power at the electric service panel and post a sign warning others not to turn it on.
  2. Remove the access panel on the electric water heater.
  3. Disconnect one of the element wires and set a multimeter to RX1000 (resistance times 1,000). Touch one probe to an element mounting bolt and the other to each element terminal screw, in turn. If the tester displays anything but infinity ( open circuit), replace the element.
  4. If necessary, set the multimeter to RX1 and touch the probes to the terminal screws. If there is any resistance reading at all ( closed circuit), then the element is good. If not, replace it. Both upper and lower elements are tested in the same manner.
  5. To remove the element, first drain the heater.
  6. Disconnect the remaining element wire. Remove the mounting bolts holding the element in place. Remove the element.
  7. Replace the heating element with one of the same model, shape, and rating. Make sure you also replace any installation gaskets.
Test and replace a high-limit cutoff:
  1. Disconnect power to the heater at the electric service panel and post a sign warning others not to turn it on.
  2. Remove the upper access panel and push the reset button.
  3. Replace the access panel and turn the power back on. If the water is hot, the reset was the problem. If not, you'll need to turn the power off again and reopen the access panel.
  4. Use a multimeter to test the cutoff terminals for continuity. If faulty, replace with an exact replacement part.

If there is no hot water, first push the reset button on the high-temperature cutoff; test the thermostat and replace if faulty (see below). Test the heating element(s) and replace if faulty

Miele wt945 won't heat when washing


Possible that the heating element is faulty. It is best to confirm using a multimeter to test the continuity of the element. If so then check the voltage on the element at the time of the cycle and if there is no voltage then the controller unit is faulty. check for fault in the connectors , wires or links.

Heating element replaced. Worked one load and back or dryer seemed very hot. Turned off and later ran on low. Next load no heat.


Hi.

There is either a problem with the thermostats that turn off the heating element, or the heating element is plugged (elements has contact to ground and stays always on).

Heating element and thermostats are tested reading Ohms with a multimeter set at Rx1. If the circuit is open (Ohms stay infinite), then the part is defective.

If the machine overheated, then the element may be gone again. Test reading Ohms.

Also replace the thermostats (there should be two or three of them), unless the element had a contact, the most common cause for overheating is a shorted thermostat.

The Dryer is starting, but shuts off after 10-15mins. It seems to be very hot. Is there an overheating element or something that can be easily replaced?


This certainly sounds like an overheating element. The problem is that the element is working. Something is allowing the element to get too hot. Then your over-limit switch is sensing the fire hazard and shutting down the system. Safety in action.
I suspect your blower fan is not running. This fan keeps the heating element from over heating by blowing the heat to the clothes in the drum. This is easily checked. The very next time you attempt to dry a load, start it and go to the exhaust vent outside. Put your hand close to it. See if it is blowing air or not. No air blowing = shut down in 10 minutes.
The blower motor should not be too hard to replace. Surely easier than the element itself. Before you pull the motor, use a multimeter to confirm that power is getting to the motor first. Power yes, motor running no, replace it.
Could also be something simple, like a wire broken or pulled off of the motor. That is why you check first. Good luck

BOTTOM ELEMENT DOES NOT WORK


If the top element is working, then it is either the element, the wiring harness , or the control board.

Since both elements are controlled through the same temperature probe, then the temp. probe should be OK.

The heating element must be removed and tested using a multimeter.

The part is tested disconnecting wiring from element contacts, setting a multimeter to read impedance at Rx1, and reading Ohms on element contact.
If the circuit is open (no continuity and infinite Ohms value), then the element has blown and must be replaced.


If the element has continuity, test the wiring harness, then replace wiring harness or control board.

All the test must be done by a trained repairer, strictly observing all health and safety rules.

Regards.

Water not heating up


If water is not heating up, parts that must be tested are the heating element, the thermostat , and finally the control assembly and wiring.

T he heating element is tested by reading continuity with a multimeter.

The thermostat can also be tested by reading impedance, that should result over 1Kohm at ambient.

If the multimeter and element read fine, then there is need to test wiring and timer control board. this is done by checking voltages at heating element and reading voltages on control board connectors. A faulty board can also be spotted by visually checking the board for burnt components or leaky and bulged capacitors.

Dometic RM2652 will not run on electricity only Propane


Most likely your heating element burned out or else the circuit board is bad. To test the heating element unplug it from the circuit board (j6 and j7 usually gold colored) take the two heating element wires and using an ohm meter make sure there is no resistance between them, if there is resistance the heating element is bad, Or can just put a plug onto the heating element and plug it into a 110 wall outlet and see if it gets hot. If it is not the heating element it is most likely the main circuit board. (between 1993-1996 dometic used a yellow epoxy filled circuit board that went out pretty quickly) if you have the yellow filled circuit board rather than the green one it is most likly the circuit board
