My Frigidaire Affinity clothes dryer has been stopping after just 5 to 10 minutes into the drying cycle. The display flashes "ad". I downloaded the manual and retrieved error code "e04" from the machine. The dryer is running firmware version r06. I can't find anywhere that can tell me what error code e04 means. Can someone please help me?
Thanks!:confused:

I got to spend some time tonight to work on the dryer. Here is exactly what happens: I put it on Normal/High Heat cycle and start it. It runs for 5 minutes and then AD comes on the display. It runs for another 5 minutes and shuts off and the display flashes error. I used the manual to pull the error code and it is code e5b. I checked the manual for this code and it means that the heating element is not coming on. When I run the dryer (for the ten minutes it'll run for before turning off) it doesn't produce any heat.

I disconnected the vent and cleaned it out as well as cleaning out the inside of the lint trap and it still did the same thing. In the manual, it says to test the voltage across relay RL2. I did this and got 0 volts. The next step in the manual was to disconnect the black wire and test the voltage drop between the red wire and the neutral. I got 240v here. So, what this tells me is that the relay is not clicking on to turn on the heat. I guess this could be because either the relay is bad or the circuit board is bad and not telling the relay to turn on.

After reading up on these dryers a bit, I found that the AD means "Additional Drying" mode. Basically what's happening is that the dryer's thermistor is detecting that there is no heat , putting it in AD mode and after no heat is detected for another 5 minutes, it shuts off and kicks the error message.

The other worrying thing that I noticed while I had the top of the machine off was that the motor seemed to be arcing. I was seeing white flashes coming from the back of the drum and I heard a ticking sound each time it flashed. This doesn't seem normal to me.
