I have a smartheat quietpak4 HE3 it had a code of F70 my kids still tried to dry clothes in it now just beeps when you open the door the drum light work but, when you push start it beeps quickly. Why

This could be a door switch issue or the belt on the drum has come off.

Try feeding the info into google

Hello Biff

You should the the following.

Level the dryer
Check the drum belt
Check the drum support rollers
Check the idler pulley
Check the glides
Check drum bearings
Check the blower
Check the baffles

What is the exact model number?

Unplug it and check the connection inside where the cord attaches to the machine. I have seen these come loose.

Hi.

Please read the article I wrote on fault codes F70 and F71. The problem is the same with all Duet models:

F70 and F71 are two logic board error codes that point at a communication error between the main log...

My Kenmore Elite dryer keeps beeping..just going through the end of cycle alarm-high,low,off...anyone have any suggestions?

Try putting less of a load in dryer. The weight of the clothes riding against the door, may be the reason why it pops open.

leave door open and press the rubber botton inside, \ I just hooked up mine and it did same thing, i pushed botton light went out, so this told me the door wasnt closing correctly, you have to push hard on door first couple times. hope this helps you.

check the door switch
