I presume the way 3 heat settings are accomplished is through the use of 2 different wattage heater elements. For example, Low = 1000w element; Medium = 1500w element; High = both elements. This may be right. Another way it can be done is with two equal wattage elements. Low = one element across 120 V, medium = one element across 240 V, high = both elements across 240 V. More common in electric ranges that have off-1-2-3-4 pushbuttons instead of "infinite" heat controls, but possible in a dryer. How is it possible for the dryer to fail in a mode that results in only medium heat? Using your assumption, "low" element open, or faulty temperature switch. Just trying to get a few ideas before opening it up. Open it up. ![]() up and taped somewhere inside the control panel. If you can read this and drive a DVM, you can make some tests of the switches and the elements at the control panel wiring, before having to pull the drum out to get at the elements. Unplug the dryer first and watch out for sharp edges of sheet metal inside it. Matt Roberds |

This GE dryer (USA 240v model) has 4 heat settings: Hi, Medium, Low, Fluff (no heat). It also has a moisture-monitoring setting ("More Dry" and "Less Dry"). I presume the way 3 heat settings are accomplished is through the use of 2 different wattage heater elements. For example, Low = 1000w element; Medium = 1500w element; High = both elements. There is now one heat setting: medium. All the settings of the heat switch result in the same medium heat. The filter screen is clean and the airflow out of the vent hose (I disconnected it and checked the flow) is unchanged from a year ago (the last time I remember checking it out). Mains voltage verified. No overheating external connections. How is it possible for the dryer to fail in a mode that results in only medium heat? Just trying to get a few ideas before opening it up. GE model DBXR453ET3WW Thanks, Consider that your dryer is not just 240V it is 120-240V any element can be running at 120V or 240V or 0V at any one time. It might also cycle, but I don't think any do that to control the temp. -- Joseph Meehan Dia duit |

Dryer elements that I've seen have all been 240v, I also had a Kenmore dryer that had separate button thermostats which cycled the element depending on the temperature setting, I figured most dryers did it this way. If you have two elements and are only getting medium then the low element is not working, either it's burned out, the overtemp thermostat is tripped or defective, or the switch is bad. |

This is wrong. 120 V across both elements in parallel will be half the wattage of 240 V across a single element. Your statement is true, but I don't think it's what I said. Maybe I wasn't clear. If you have two 100 W 240 V elements, putting one element across 120 V yields 25 W. Putting one element across 240 V yields 100 W, and putting both elements in parallel across 240 V yields 200 W. Now I agree that this isn't a very linear progression (25-100-200), but I was just using it as an example. Matt Roberds |
