iCEMAKER?

My icemaker on my GE frigerator is acting up. A few weks back i noticed that water had leaked from the icemaker and when i pulled ou the bin i could see that the ice was melting. i removed the bin dumped the remaining ice and turned off the icemaker. I waited a day or two then turned the icemaker back on and i has been fine since till today. same problem again.
What should i be looking at to fix this problem?
