I have a Lennox HS-18 Heat Pump. I recently had a problem with a dirty air filter and was told if the same problem occored again to open the outside unit and press the red reset button. The problem was because of restricted air flow the unit sensed a problem and shut down the outside unit, leaving the inside blower blowing cool air continuosly.
I changed the filter and reset the switch. When I do that I hear a clicking noise on some sort of a switch above. But this switch never actually makes contact to allow the unit to go on. If I touch the switch it will make contact and work, however once the temp gets to the thermostat setting the unit goes off and won't go back on.
Does anyone have an idea if I am doing something wrong or does this sound like another problem? I plan on calling the serviceman again but I wanted to check here as well!
Also, anyone have a ROUGH idea how much a complete new unit installed might run? This thing seems ancient and inefficient. Just a ball park figure would be appreciated!
