I have a Cabrio Steam dryer that I have had for a little over a year, figures just out of warranty, and the display lights come on, but nothing happens when I hit the start button. I found the tech sheet under the control panel and ran the diag tests on it and came up with code "F25". Says to replace the inlet thermistor, which I did, and it still did not fix issue, so I replaced the next logical thing, the thermal fuse. This should have been the first logical thing. It seemed to run great for about two weeks and then the same thing happened, display lights, but won’t start. Thermal fuse is bad again, so I am bypassing the fuse to run more tests. The diag test still shows the "F25" code and I do not know why unless I installed a bad "new" thermistor to begin with. I cleaned out all possible places that could store up lint, wasn’t much to speak of. I believe the heat outlet in the wall goes straight up and out through the roof, which I believe is a poor design because of gravity. I tried running dryer in Timed Dry and Air Only mode and the dryer heat is coming on. It should not, correct? I know, a lot of info to digest, but I wanted to be as thorough as possible. Please advise! Thank You, Kevin
You are correct air only should not have any heat.
Check the heating coil.
Unplug the unit and both wires to the coil.
Check it with a meter, should be around 10 to 12 ohms.
Then check from each side of the coil to the case/frame, both should be infinite ohms (open). If not the coil may have sagged or broken and is touching the case. This can cause it to run and the thermostats cannot regulate it.
