Oven is slow to heat up and will not heat above 250


You may have a bad heater coil in the oven or have lost a leg in the 220 line. Check and reset the breaker 1st then check the voltage in the receptacle. It should be 110 from each leg to ground and 220 across the hot legs.

Wont get hot


Most likely burned out heating element. Does the broil work? If your handy turn off the circuit breaker making sure power is truly off by turning on oven to verify it won't turn on. Remove the screws from the bottom heating element remove the wires and take it to your local appliance supply house, they might test it for you and they can surely sell you a new one just by the the shape alone.

I turned on the self cleaning and the door locked but is the heat supposed to go on and off


Yes. It is maintaining a temperature hot enough to burn off residue but not overheat and burn the house down. It should be running somewhere around 500 degrees f

F2 low temp


The most common probem is burned wires going to the heater on the top of the oven cavity. Typically you will see the coating on the wire close to the heater all cracked and bare. You can usually just cut the wire back an inch and pull some slack up and reconnect the wire and you will be good. In some cases the wire will be burned to much and the whole wire will need to be changed. Any oven repair shop will sell you these high temp wires. DO NOT use regular wires they MUST be high temp rated.

Here is some other things to check if the heater wires look good.

COMPONENTS
IR Element
The IR element - a dual coil type heater - is located
in the bottom of the oven cavity. The first coil is the
heating coil. The second is the IR thermocouple
wire. The heating coil outputs 3000 watts at 208
VAC. The heating coil's resistance is 14.4 ohms at
room temperature.
The thermocouple coil is a Type K thermocouple
with a resistance of approximately 20 ohms at the
splices located approximately 6 inches from the
heater and 40 ohms measured at the extension wires
at the I/O control board.
The IR element is controlled via the K5 solid state
relay and the IR thermocouple via the I/O control
board.

Also try this

1. Verify the high-limit thermostat is not tripped.
o If high-limit is tripped, reset and allow the oven to warm up.
o If high-limit is not tripped, follow the instructions below.
High-limit thermostat is not tripped.
Place a small water load in a microwave/heat-resistant container
(approx. 275 ml) in the oven and place the oven in TEST MODE. Press
the MGTRON key to actuate the microwave. While holding down the
MGTRON key, watch the CC and IR temperatures. If either temperature
bounces substantially, there may be a noise (EMI) problem.
To correct this problem, examine the wire routing for each
thermocouple wire. If the wires are routed near any high voltage
components such as the magnetron or high voltage transformers, reroute
the wires. If this does not correct the problem, verify that both
magnetrons are securely mounted.

Good Luck

Built in oven won't get hot


hello there
Usually, when an oven won't heat up or bake, it's because the bake element is burned out. The bake element is the black, pencil- thick tube at the bottom of the oven. When the oven heats, the element glows red. This element has an expected life-span of several years. It may last for only one; it may last for many more. When the element burns out, you need to replace it. Now if the oven It bakes poorly Here are two instances of when food "bakes poorly:" When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out. You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results. If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component. When the temperature is consistent but too high or too low, it could be one of several different things. First check to see if the thermostat sensing bulb has come loose from its holder. It could be lying on the floor of the oven or resting on the heating element. This would cause the oven to not heat correctly. If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective. Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details. Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat. If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem
Hope thisis very helpful for you
Best regards Michael .

Our heater is 3yrs old and it is giving off a metalic smell when the hot water tap is turned on. We have had other hot water tanks and never had this problem. This is the first Moffat hot water tank we...


This may sound strange, but here is what to do. (the full explaination is rather long)

Turn power off to the heater. Turn off water supply to heater. Drain at least a gallon of water out of the heater and diconnect one of the pipes at the top. Add a gallon of bleach. Reconnect pipe. Turn water back on to heater and run each hot water faucet in the house until you can detect the odor of bleach, then shut them off. Let the system stand for at least an hour. Now, turn each valve back on and run until the odor of bleach is gone. Turn power back on to heater.

The Lower oven does not heat up.


It could be either the heater element itself that has failed or the thermostat switch is faulty. You need to have them checked over with a multimeter or a continuity tester to establish which. Do this with the power off.

Oven staying hot a long time after it was turned off


Thanks for your reply. I contacted an appliance repair person I have used before and he told me about turning off the breaker, which I did. He suggested using an oven thermostat to see if it was heating to the correct temperature as a first step. It may be the thermostat, I do not know what the controller is as presented by one of the responders. At any rate I learned that my breaker for the oven is by itself and is not attached to the stovetop which is good. I will have to weigh the cost of replacing a part on a 20 year old builder quality oven with microwave on top to a new one. Any ideas on a new problem free model are appreciated!!
