Dryer heats even on no heat/air fluff setting.

by Andrew Orsak
(Warner Robins Ga USA)

I have a roper RED4340sq1, i have changed both sensors on the heating element can & the blown fuse on the fan motor housing. I have not changed the cycling switch on the fan housing. It gets hot, but it gets hot & i can see the heating element glow red even on air/no heat setting.

The unit isn't very old, and didn't want to change the timer just yet. I did put a meter on the two wires controling the power to the heater, and during cool down i loose continuity. Any suggestions?

The first thing you need to check is the heating element. What can and sometimes happen is that the element will ground out. This means that eh element will not burn out but will touch the side of the heater-can. This will cause it to heat even if the dryer controls are not calling for heat.

To check this disconnect the power to the dryer and disconnect the wires to the heating element. Place your meter to the highest setting and test for continuity from one of the terminals to ground (the heater-can). If there is continuity the element is bad, replace it. If you are uncomfortable using the meter you can remove the heater and look to see if the heater is touching ground anywhere.

If there is not post a comment and we will go from there.

Thank you,

Found broken heater element insulator allowing the element to ground itself against the heater housing, calling for heat all the time.
A BIG THANKS.
