Question about Maytag M3DH30B2A Dehumidifier
After I plug in the device, I turn it on and select a setting. Immediately the fan starts blowing. After a few seconds, the compressor (I assume its the compressor) turns on for approx. 6 seconds, then turns off. The fan runs for another 30 seconds, the compressor comes back on for another 6 seconds. This process repeats, and no water is collected. I purchased the dehumidifier from a friend, and it's about 3 years old. Any ideas? e

Sounds like the low pressure cutout switch is stopping your compressor running, especially if the "6 seconds" you mention are exactly the same length. Not enough refrigerant would be the usual cause, but the reason for the refrigerant loss is harder to tie down - possibly a seal or a loose valve seat or even a pinhole in a copper tube. Best solution now would be to take it to a refrigerator mechanic to top it up and check for leaks - get a quote first to check - 'fridge gas is getting costly. Other possible solution is that the low pressure switch itself is faulty, relatively inexpensive to replace (but unfortunately you will need at least a partial gas recharge on most types of system after) - your fridge gas guy will be able to check very easily if there is adequate gas in the system, and should check this low pressure switch if there is not.
