At his time of year (depending on your location), yes it is normal. I have one in my basement and when winter hits, it will still come on but the compressor doesn't kick in because the humidity level is very low, so I wind up shutting it off for the winter months. It will blow cooler air for the same reasons. The compressor is producing the heat. If just the fan is on it's just circulating the air. Now if you live in FL and have humidity year round and the compressor is not kicking on there may be a problem. Try opening it up and cleaning it out, and definitely clean the filter. Many times when the humidistat isn't working properly, it just needs a good cleaning and it will work fine.

Using as heater and unit is blowing cold air

A heat pump is an air conditioner that reverses its refrigerant flow. In the cooling mode, the evaporator is cold to the room and its condenser is hot. In the heating mode, a valve reverses the refrigerant flow and makes the evaporator warm and the condenser cold.

Using heater...cold air out of the back

With heat pumps that's the way they work. In heat mode they are using the evaporator as the condenser and it blows heat out the front and cold out the back. In cooling mode, a reversing valve switches the gas flow reversing the operation of the coils and it blows cold out the front and heat out the back.

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.

It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

Blows cold air,but no condensed water

To condense the water (cold side) the air should be warm.

Sounds like coolant leak or compressor problem; if so, time for new unit.

Unit blows out cold air while on dehumidifier

Liz; Check for a fuse somewhere in the heat circuit. The master breaker in the house panel also

The dehumidifier is blow cold air

Is it collecting water? The air coming out the back top half should be cool/warm. It will be a little warmer at the bottom near the compressor.

Iced up coils and will not dehumidify

I did a little digging around on the internet and found out that if the basement (or where ever you have your unit) is in an area where the room temp might dip below 65 degrees the coils may start to become "too efficient" in pulling the moisture/humidity out of the air and it begins to freeze on the coils before it can drip off into the reservoir. The site said to turn off the unit and let it thaw out, then restart it and see if everything works ok after that. If the temperature gets too low you might need to warm up the air in the room/basement before it will operate correctly again/not continue to freeze up. Hope this helps. Mine just did the same thing but we've had some pretty cold weather recently and the basement is fairly cold as well.

A common problem - low on refrigerant. Unfortunately it's not a simple fix. Check your warranty to see if you're still covered for "Sealed system repairs"
