What type of Thermostat is this? If it is a Comfort Control Center, four or five button, then turn off the thermostat, hold down the mode and zone buttons at the same time and turn the tstat back on. When EE appears on the screen, then release the button and see if it begins to work. If not, then we need to check the control unit in the AC. Hopefully it is just a simple reset.

I have a built in wall oven whirlpool gold mod.gbs309pvsoo controls turn on but no heat from element


Could be element could be Hi limit thermostat could be control. In that order. First step is turn breaker off and remove element to make sure the wires are still connected to back of element. Visually inspect element very good for burns or a white powder residue signally the element burned up. Next step is harder, need to remove the oven and take off back panel, there you will find the hi temp thermostat. Check for continuity, if none replace.

Start shut down


follow this steps and use the Voltmeter, and fix it. God bless you
oubleshoot a thermostat:
  1. Shut off power to the heater at the electric panel and post a sign warning others not to turn it on.
  2. Unscrew and remove the electric water heater access panel.
  3. Using a small screwdriver, turn the thermostat dial counterclockwise to lower the temperature, or clockwise to raise it. If the water heater doesn't maintain the proper temperature, test the thermostat.
  4. Disconnect one wire to the upper thermostat to test it. Set a multimeter to RX1 (resistance times 1) and touch a probe to the thermostat terminals as indicated in the owner's manual. Depending on the model and the terminals tested, the tester should show infinity ( open) or about 0 ( closed).
  5. Test the lower thermostat in the same manner.
  6. If necessary, replace the thermostat. Unscrew it from its mounting and install one of the same model, size, and rating. Once you install it, adjust the thermostat following instructions in your owner's manual.
Test and replace a heating element:
  1. Turn off power at the electric 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 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.

Some elements is in Short circuit, test the procedure before

My refrigerator temp control knob is turned all the way up and the temp will only get down to 40 degrees.


Defrost Problem
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.
OR
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

How do I turn up the water temperature on a Marathon 85 gallon electric water heater? I don't see any visible temperature control settings.


The temperature is controlled on the thermostats in the tank. They are under the two covers you see on the outside of the tank. There is an upper and lower thermostat. Make sure you shut off the power before you begin. Remove the cover and peel back the insulation covering the thermostat. Use a flat head screwdriver to adjust temp. There should be a pointer showing the temp its on now. They are probably set at 120 degrees. WARNING--turning your hot water temp above this point can cause scalding and burning in less than 3 seconds. You may have a burnt out lower element. This link below should help you

This is the manual to your tank. Good luck.

Heat will not turn off.Removed thermostat wile


Hello
Could be a stuck control relay,Tsat completes a circut for this relay to engage,once relay contacts are closed heater will start.and stay on until you reach temp.

once temp is reached relay will open and heat will shut down.

By disconnecting all power to heater your forceing relay to open.or simulating a satisfied temp.

I would have a service tech look at your control relay and t stat.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

Water temp


The water heater thermostat control is usually under a plate/cover toward the bottom of the water heater. Remove the cover (first turn off the power to the water heater) and look for a dial with temperatures marked on it.

You can adjust the thermostat using its knob (if it has one) or a screwdriver. There may be insulation covering the thermostat, so you may have to pull some of that out of the way to see the thermostat.

You most likely have a bad thermostat control or a bad defrost timer.
Locate the defrost timer, probably inside the temp control panel.Defrost cycles should last 30 minutes then resume freezing.
Manually turn the timer control a 1/4 turn and see if it starts.
If so, replace the defrost control.

It could also be a bad temp control.
If the timer adjustment does not start the fridge. Tap the temp control. It may have stuck contacts.
