Mr. Slim Problem - Please Help

[darrenw2112]

I have a Mr. Slim Heat Pump which has the following problem. When you initially turn it on and set the temperature, it will heat up (over shoots a little) and then shut off when warm. The problem is that once it shuts off, it will only stay off for a couple minutes (maybe 5min), and then turn on again for just a little while (from 10 sec to 1 min). Then it just continues this cycle (on for a little while(a couple seconds to a min, off for 3-8 min). I have had all of the PC boards in the inside unit replaced and it still acts the same way. There are no fault codes stored in the unit. This is one of the new units which takes R410A.

Thank you in advance.

If you are a DIY'er, these type of questions are not allowed here. The best thing you can do is call a pro to give it a look.

If you are a tech, I would try giving Mit. tech support a call or applying for pro membership here and posting this question in the pro forum.
