    I had an RDE20.1 stuck on and temp reading 28.5. Fixed by first replacing battery (battery symbol was on), then changing the desired temp to above 28.5 (30) which made it switch the relay on (triangle came on, but no clunk), then set desired to below 28.5 (10) which made it switch the relay off again (triangle off and this time the successful clunk was heard!). Worked fine after that.

check your circuit breakers to see if the floor is getting power to it. Consult your operation guide to see if there is an internal fuse.

Tip

Underfloor Radiant Heating works great with a Geothermal Heat Pump


Radiant floor heating has been the standard for comfort and efficiency for many years. The feeling of having a warm floor under your bare feet is priceless. Rolling on the floor while playing with your children or grandchildren is great when it is cold outside and the floor is pleasantly warm.

Geothermal Heat Pumps usually are associated with hot air heating and air conditioning systems. If you live in a climate that very seldom needs air conditioning, then you need to concentrate more on the heating. There is a super way to use geothermal technology to give you very efficient and comfortable heating. Underfloor radiant heating can very easily be incorporated with a geothermal heat pump to give you the best of both comfort and efficiency.

Here are some thing’s that you do have to consider before deciding on a system like this.
You will need to drill a few wells to extract the heat from the ground.
Piping must be installed in the wells correctly for the system to work properly.
You will need a heat pump designed for hot water heating.
You can not use a heat pump that is designed for hot air use and convert it for radiant heating.
The radiant heat design must be designed to use water temperatures that are cooler than that of many radiant heat systems.
The maximum temperature design should be 130 degrees F.
To get this kind of design to work correctly for you, you will need to use good quality heat plates and insulated under the heat plates.
By following these guidelines I have designed a number of radiant heating systems that have proven to heat houses very comfortably at temperatures well below zero.

If you decide on installing this type of system make sure that your installer knows exactly what they are doing. This type of system requires many things to be done exactly right, so that the water flows will allow the system to work correctly. The piping on the well side is extremely critical so that it uses all the wells equally. On the house side the piped using a primary/secondary piping scheme. Pumps and pipe sizes need to be able to give you very high flow rates so that the temperature drop is kept to ten degrees or less. When working with these low temperatures the piping and pumping becomes so much more critical.

By using these principles you can combine two very great heating types and can have a very good heating system that will perform very well for many years. The main drawback with this type of system is that you do not have the ability to get much cooling from this system. This is probably the only drawback of this type of system. It would be wondeful if there was a geothermal unit that was heating only. The elimination of the reversing valve would be a great cost savings and a plus overall. This system is best suited for cooler climates that require little or no air conditioning.

Ge profile oven lock button won't go off


  • 1.Press the "Clear/Off" button on the control panel to reset the oven. This will clear the lock setting and unlock the door.

    2.Allow the oven to cool to room temperature to avoid turning the lock on again during this heating cycle.

    3.Reset the oven to the temperature you require to finish cooking by pressing the correct temperature control on the control pad.

  • 1.If your GE Profile microwave won't turn on, unplug it, then plug it back in. A power outage may have occurred due to a power surge. Check your home's fuses and circuit breakers.

    2.Set the clock of your GE Profile microwave. Certain models will not operate until you set the clock. Select the "Clock" key and type in the correct time.

  • 3.Hold down your microwave's "Off" button. You may have accidentally hit the control-lock feature on your GE Profile microwave. Hold down the "Off" button for three seconds to turn the lock off.

  • 4.If the sensors of your GE Profile microwave are not working correctly, remove the food from the machine. If the sensors detect food-surface temperatures over 200 degrees Fahrenheit, it will not work properly until the area cools down.

  • 5.Contact GE Support if you are unable to resolve the issue on your own. Call the GE Support hotline or browse the help library on the GE website. You can also schedule a service visit on GE's website.

    These Tankless water heaters attempt to heat water as it quickly travels through a short series of heated copper pipes. A high volume of water at an accelerated speed has little time to heat up as it passes through its heating source. You can turn up the temperature (which you undoubtably tried) and turn the water volume all the way down. These settings will produce the hottest temperature capable of the unit - given the entry temperature of your water source.
    Most underground water enters at app 52 degrees - and becomes even colder due to ambient temperatures. Difficult to raise this temperature 60-70 degrees in a few seconds of heating.
    I've routed a series of copper pipes adjesent to the home heating system in an attempt to pre-heat incomming water. It's only a few degrees warmer, but results a 20- 30 degree hotter delivery.
    I have installed some top end units that simply delivers Hot water without compermise.

    A common problem with a particular batch of thermostats, We have sold hundreds of them .The reset occurs with high humidity eg steam. This resets the unit. The solution is to use circuit board sealant on the back of the circuit board and problem disappears forever.
