I cannot open the CD door on my Detrola KM837 4 in 1. I push the open button, sounds are emitted like it wants to work, but does not. Any suggestions?

How old is this unit? This sounds like an issue with something on the circuit board inside the player. I would suggest you take it to a specialist as this is something you probably won't be able fix yourself.

Sounds like a bad magnatron (the part that emits microwave energy) or maybe just a bad door switch. If the door switch is bad it won't let the unit come on.

the "paper clip trick" isn't a trick. It is a MANUAL way to open the door far enough to pull it open and remove the contents. Straighten out the clip. Place it through the tiny hole just above the eject button. Be sure to push it straight in. When you feel resistance, push HARD. the door should open about a halt inch and allow you pull it all the open. It will not open automatically from a paper clip.

Thank you for the solution of moving the arm to the right and wait for the click, now my turntable works and Keely Smith is playing and sounding great!

it cant be open anymore unless you bring it to the technician. don't force to open.

below the push button their is a tiny whole , take a needle of about 3---4 inches in length and insert in that whole and your door will slightly comes out then open it with your fingers

Sounds like a jam in the mech

sounds like it is out of synch.do you have a manual on this model

I have a Memorex 52x CD burner. It bought it new and had no problems until about a year after I purchased it. Then suddenly, for no obvious reason, the drive would not open. The light flashed and I could hear the gears trying to open, but it would not consistently open. If I repeatedly pushed the button, eventually it would open.

What I finally discovered is that as long as I keep a disc in the drive, it will open and close with no problems. Now I keep a blank CD in the drive at all times, and so far the problem has stopped. I suggest keeping a blank CD in the drive so you don't lose a "real" CD forever (or have to destroy the burner to get it out). I don't know if this will work for everyone.

I DO NOT suggest inserting a credit card as another poster suggested. I tried this and it DOES NOT work. Plus you risk breaking the drive and destroying your credit card all at the same time (thereby delaying the purchase of a new one). Besides, credit card simply doesn't fit into the very small space around the tray door.

Based on other people's comments and the problems I've experienced, I'd suggest that people avoid buying Memorex products altogether. I bought this drive because my old one died and I was looking for a cheap burner to hold me over until I could afford to replace my computer. I may have saved a little money, but in the end I got what I paid for. My sympathies to anyone who's also experienced this problem.
