It over heats after 2 hours - Dell 1210S Projector

I have a Fujitsu and found that disconnecting from mains power at the breaker for 2 hours did a better reset. When you turn back on, you can hear the condenser unit outside doing a self test.

"Fisher washer stays on clen for over 3 hours" ???
I think you mean the "Dishwasher stays in the clean cycle for over 3 hours", right? First question is "What cycle?" If it's the Pots and Pans cycle, or "Pro-wash cycle" , or "Normal cycle with extra wash heat or sani-rinse options selected, then yes, this is normal! A Normal cycle (without added heat) will take about 2 hours. And a short or quick or 1-hour cycle will take less.

1) Test elements, and if elements check out, then replace both thermostats.

Is the water going into dishwasher at 120 degrees or close to it. Are you using rinse aid. If you use options like dry heat it will take 2 hours. 2 hours is normal.

Most crockpots have only two settings: low and high/heat. Use the high/heat setting for dishes that will cook in 2-4 hours. The low setting is for your "all day" cooking, typically 6-8 hours.

Hope this helps.

Ariston and on and on...lol

The water temp thermostat is to blame or the water is not heating.Basically what happens is the washer fills with cold water and starts to wash and heat at the same time.Once the water reaches a certain temperature it moves onto the next stage of the wash program.If the water is not heating or the thermostat is not working the programmer wont get the signal to move on.Hope this helps.

Smart wash: 2 hours Anti-bacterial wash: 2.5 hours Normal wash: 2 hours China/Gentle: 1.5 hours Quick Rinse: 10 minutes
Note: If water temperature is low the times shown above will be extended to allow for water heating time.
This information is from page 14 of the manual.

Your oven control module is gone. Replace.

Yes. DO NOT USE IT UNTIL IT IS FIXED! Carbon monoxide can kill you! Most manufactures will warrant their heat exchangers on 80% furnaces for twenty years. Some models only ten years.
Tubular heat exchangers are known to be very durable. If this went bad this fast the most common cause would be a faulty installation. The installer should have adjusted the gas pressure to assure proper firing of the burners. The air flow should have been adjusted according to that models rated temperature rise. And the flue pipe needed to have the proper rise, length, diameter and height to properly discharge the moist flue gases.
Get a new heating guy. Even though you have a heat exchanger warranty that will cover only parts, not labor. Unless your installer sold you a ten year parts and labor warranty. A contractor will probably charge you a flat fee of $300 -$400. or an hourly rate with trip charge and 1 1/2 - 4 hours labor. A good tech should be in and out of your home in 1 1/2 - 2 hours.
Good luck

the bulb might be getting old causing it to over heat and turn off.
