ac heat pump
I have a 2007 Fleetwood Discovery. On one of my AC units when in the heat mode, it only delivers unheated air. When in the AC mode it delivers cold air.
heating element???

That's probably you issue. From my recent research it' just an added heat coil up top. Maybe that coil went bad like they sometimes do in a clothes dryer. I just saw an advertisement for Camping World today where they had some heat coils on sale along with all the other AC/Heat pump units. I think they're by brand but all look very similar.

Is it an A/C with aux heat strip or is it a heat pump?

If your unit has auxiliary strip heat there is a fusible link in series with the heating coil. With the power turned off check it with your ohm meter as you would a fuse. They are replacible. I assume you turned the units thermostat high enough to activate the heat ? If it is a heat pump rather then auxiliary electric heat they generally don't produce any heat with the outside air below 40 degrees Fahrenheit as they have low air temp. Lockouts.

On some MH only one is a heat pump. Has it worked before?

Answers to all - Yes it has worked before. Both units have heat pumps - at least that's what the brochures say. Thanks guys.

No "heating element" if it's a heat pump. There is a thing called a reversing valve that converts the compressor from a cooler to a heater, aka runs the cycle backwards. The valve is stuck in the cooling mode. I'm not sure it is repairable on an RV unit (the basic compressor unit is not designed for repair or replacement).

Might use the "Tap it Method" sometimes they stick and a light tap might set it Free.
Just a thought,

When in heat mode do you hear compressor cut on? Heat pumps are a option.

If the outside air temp is above 40 degrees and the compressor is running you should be able to hear the reversing valve swish as it is de energized or vice vera. If you hear it I would say it isn't stuck.

Thanks to all for your guidance. Will look at the "tap" miracle - then to the shop if that does not work.

What brand is it, some work by activating the reversing valve for heating, some are the other way around and activate the reversing valve for cooling. If it is a Coleman which I think activates for heating then you may have a bad solenoid coil which is an east $30 fix. If a Dometic it may be another problem as they default to heat when the coil is bad.
