lenox heat pump on cool it blows heat it has been a while since it was last run the reversing valve sol. is clicking like it is working but the four way valve seems stuck is there a way to free it?

 

Hi,

First check and see if the Secondary/Emergency/Back-up Heat (Electric coils/strips,Gas Burners,etc...) is on with A/C.

If not,then check and see if compressor (Outside unit-Turn off power,remove panel,wait ten minutes,restore power) is running (Look and Listen for it to start) and if it is, see if air blowing out of/off Condensing Unit (Outside Unit) is warm/hot or cool/cold.When doing this,anytime you turn off unit,wait 10 minutes before turning back on.

Also make sure Outside/Inside Coils and the Filter is clean.


If Sec. Heat/Back-up Heat is OFF,Compressor is running,coils/filter clean and air coming from vents inside is warm/hot and air from outside Condensing Unit is cool/cold,Reversing Valve probably stuck in Heat Mode.Turn off unit,wait 30 minutes and turn back on.If it is the same and t-stat is set to cool/auto (Could be faulty t-stat also not switching to cool), I would call a Qualified/reputable Heat Pump Contractor to inspect it. Would not advise tampering with Reversing Valve.Hope this helps,please keep us posted/updated.Take Care and Best Wishes.
