Trane XE 800 stuck in defrost

I noticed that my unit was making a lot of noise, so I went to look and the metal housing that the motor mounts to is starting to rust/break loose. Now it just seems stuck in defrost mode. My heat seems to be working fine, but the outside unit just hums. I need to find a way to replace the housing if the fan does kick on again.

I turned everything off for 10 hours, hoping that that would defrost the ice buildup. We didn't get down to freezing last night.

When I turn the fan on, nothing happens.

If your unit was stuck in defrost..... you wouldn't get any heat in the house.
Defrost mode is the system running in A/C.

When in defrost.... the condenser fan can cycle on and off.
When it goes back to heating mode.... the fan should be running.
If the fan is just humming.... the motor may be bad.

Thanks Pete, its all frozen inside. I'll put a new motor on it. Any idea how to fix the part that the motor bolts to?
The sun came out, so there is no ice in there now.

If the unit is frozen inside and I hope that you mean the outdoor coil, that means that the outdoor unit is not defrosting as it should. You probably have problems other than the fan motor. Before you spend money foolishly I would have an HVAC guy service this unit to see just what is wrong. The fact that the fan is not running does not mean that it is bad.There may be a control that is not allowing it to run.
