The heating number never stays where you set it and the L will stay on

computer board has failed.

Stays on because it can not satisfy the tstat or continues to heat past set point

button or switch sounds dodgy

You are setting the temperature on temporary hold. It stays there until it reaches the time of the next programmed sequence which is away or leave and it jumps back on the program. If you want it to stay all the time where you set it you can push the setting up to the desired temp and push hold. It will stay there permanently until you push run which will put it back on the program if you want. Or just push set and program the whole sequence the way you want then press run.

If your heating element is grounded (wire burnt in half and is touching metal) the heat will stay on forever, even in air fluff. This is your most likely problem.

that isn't the model number,it will start with 110. or 417.send the full model number and i can look up your dryer,most likely it's the even heat board or the motor relay but without the model number i can't look it up for you,these parts are in the top console,call the parts store give them the model number and they'll give you the right part or send it to me,let me know what you find

Do you have the serial number or the manufacture date? There are some design changes and I would need to know the year of manufacture to assist accurately. Usually it is a relay or the thermocouple connection that will affect the unit staying lit.

If you have an ML300HGA, it is a manual-control heater, which means you turn it on and you turn it off. No thermostat. It does not have an AUTO setting.

Likewise, the thermostat-controlled models do not have a Manual mode. If you have the ML300TBA, it has a thermostat and will turn itself on/off in order to maintain a room temperature.

On manual models, the numbers (if any) on the dial are heat output selections. Set the control to the highest heat setting and that's what it does until you turn it off.

On automatic thermostat models, the numbers on the dial are temperature selections. Set the control to the highest heat setting and the heater will continue running until it is 85-90 degrees, then shut off. Set it around 2 and it will maintain a temp of around 70 degrees.

All Procom heaters are either automatic (thermostat-controlled) or Manual. None are both.

I called Cuisinarts repair center and they had me set my auto off button. It had been set to 0 so it shut off as soon as it started brewing. If you turn the switch to auto off, then when the numbers are blinking hit the hour button until you get the desired hours you want the heating element to stay on. Then when you stop hitting it it will remain at that time after you brew your coffee. If that doesn't work you can call the help line at 800-726-0190, just give them your model number and serial number, the device carries a 3 year warentee
