Disconect the heatind element or elements on the live side and see if it still trips the 20 amp breaker. try that first.

Frigidaire stove model CFEF372EC3 Ser #NF60720192

Things to check : Thermostat, heating element and the circuit breaker for the stove at the power panel. If the stove has lights and the clock works, there is a 100 % chance the circuit breaker is at fault. There are 2 breakers with joined trip handles. One of those breakers has tripped without tripping the other which stops 20 volts but not 120 volts that the clock and light run off of. You can use a multimeter to check the element for continuity. If there is continuity then check for the presence of voltage at the element terminals. None indicates a bad thermostat.

How to replace a fuse in a hotpoint

Check the circuit breaker for the plug the dryer uses. Open your house power panel and locate the breaker for the dryer. It will be 2 breakers connected together by a metal pin so when one trips it will trip the other. This shuts off 240 volts. Sometimes only one breaker will trip without tripping the other one. This leaves the dryer with 115 volts to work the rest of the machine but won't power the heating element. Replacing the breaker will fix the dryer.

My astra espresso mega 2 s boiler pressure is 0.

It is possible that the safety thermostat on the boiler has tripped. Reset safety thermostat and turn machine on. If reset is not tripped then it could be the element or the pressure stat are damaged.

Not drying clothes

First check your breakers in the main box. The dryer lights and drum will spin with 110 volts only the heating element needs 220 volt if one of the breakers or fuses are tripped it will not heat. Trip the breakers off then turn them back on and check it. If it still wont heat check the heating element and wires leading to it as well as the 110/ 220 volt connector it may be bad or have a wire off, if all is ok then the heating element is probably bad and a new one needs put on.

I have a Rheem Model # 82V52-2 and its being supplied by 25 amp breakers. They do not trip out but the 100 amp main gets real hot and trips out and I believe it happens when the water heater is in use- any...

The Rheem water heater uses 4500 Watt elements
Check label on side of any appliance to see electrical rating details
2 element tank with two 4500 watt elements is still a 4500 watt appliance since both elements are never ON at same time.

Volts x amps = watts
amps = watts divided by volts

amps = 4500 divided by 240Volts or 220Volts
amps = 18.75
Your water heater uses 18.75 amps to 20.45 amps

Your 25 amp breaker should only carry 80% of rated value
25 amps x 80% = 20 amps.

So your water heater breaker is correctly sized.
You should have a 10 gauge wire going to this water heater.
12 gauge wire is a bit undersized for 4500 Watt water heater
Feel the water heater wire to see if it is warm.

If the main breaker is getting hot when 20 additional amps are being used by the water heater.
1) The house is using more amps than your 100 amp main can carry
Using the formula, 100 amps x 80% = 80 amps for the main breaker
Add up your total amp draw.
For example if your 3500 watt oven is ON, it draws 16 amps.
If your 5000 Watt electric heater is on, it draws 23 amps.
Your 1500 Watt 120V microwave draws 12.5 amps.
Add these numbers up plus your water heater, and it comes to 71 amps.
71 amps is getting close to the max 80 amp, but it's not over.
Now if you have a pool pump and and hot tub and a table saw going, the main breaker could be overdrawn.

2) To solve the problem short-term, you can put a timer on the water heater and use it only when needed.

3) The main breaker is bad and needs to be replaced.

If you need help figuring circuits or timers, add a comment and I will help

The hot water heater should come with an amperage rating on it.
They vary from 30 to 40 amps, and then 10 or 8 gauge wire.
(All hot water heaters are 220 volt.)
I believe the 602 uses a 4500 watt element.
Divide 4500 by 220, and you get about 20 amps.

If you want to be on the safe side, you go with the heavier wire, 8 gauge, and then go with the smaller breaker that is more easily tripped, 30 amps. That way you can switch to a 40 amp breaker in the future, without having to change the wiring. The goal is to always make sure the wire is rated higher than the breaker. You want you breaker to trip before your wire melts.
But technically a 30 amp breaker and 10 gauge wire would be fine for this heater.

And since it is 220 volt, you will always use a double breaker.
That is because 220 volt appliances don't use a ground, but instead use the potential between to power wires that are 180 degrees out of phase. AC always does a sine wave, and the 2 power leads coming into the house are always out of phase. When one is 110 volts up, the other is down. So the total between them is 220 volts. And the way they intentionally zigzag the breaker box, 2 breakers next to each other always are on opposite power lines.

If you have any doubts at all about 220 and water heater wiring, please ask again. Wiring is not hard, but you have to understand what you are doing, or else you can cause serious consequences.
For example, if you use wire nuts or wrap wire around a screw, you need to always turn them clockwise, so they pull the wire when tightened.
You also always need to ground the chassis with a green safety wire.
Since a 220 hot water heater uses 2 power wires and a safety ground, the white wire should be striped with a permanent marker, so that it is not confused with the white neutral wire of a 110 volt appliance.

My Whirlpool Ultimate Care II dryer does not heat up, however it does tumble. Any help would be greatly appreciated. Thanks.

There's no heat If your dryer doesn't heat, check these: Power from the house Heating element Thermal fuse Wiring Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected. Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable. Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.) Wiring A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

No heat in dryer


Thanks for using FixYa. If your dryer isn't working or isn't getting heated up, you'll need to check the following to be sure what exactly the issue is--

Blows fuses or trips circuit breaker —ELECTRIC Models:
• The amperage readings are at 240 volts. One line will be 24 amps and the other line will be 21 amps. The neutral line will be at 3 amps. If the above amperages are not present, then the house wiring, fuse box or circuit breaker should be suspect.
• Shorted heating element to housing.
• Incorrect wiring or a wire shorting to ground.
• Drive motor winding shorting to ground.

Blows fuses or trips circuit breaker —GAS Models:
• If igniter is not glowing, check for 120 V at igniter.
• Igniter harness may be loose and shorted to base.
• Incorrect wiring or a wire shorted to ground.
• Drive motor winding shorting to ground.

If it runs for a few minutes and then stops, then check for the following:--
• Empty dryer.
• Check motor spins freely.
• Lint buildup around drive motor.
• Low voltage present.
• Blower impeller blocked in blower housing.
• Drive motor - start switch contacts stuck closed.

Please do rate the solution and revert for further assistance.

I need to know what the ohms reading should be for the heating element for a kenmore elite dryer model # 110 63022101

All dryer elements should read between 10 and 15 ohms. A burnt one wil be very high in the kilo or mega Ohms, most likely open. A shorted system will read zero to half an ohm depending on your test leads and their connection and this condition will trip the circuit protection. A damaged element my read 30 to 100 depending on the severity. You figure 220 volts divided by 12.5 Ohms is abot 18 amps, which is just what household wiring like. It can take 40 but most of your circuit breakers are 20 amp slow trips. I hope this clears up the issue for you.
