RUDD A/C not running, only fan

I had a RUDD unit installed last year at a condo at the beach. We arrived tonight and only the fan is running. When I go to look at unit outside, it isn't running. We've looked at the fuse box and thought of any way it's not getting power but can't figure it out. I'm sure the last time it was turned on because we do not rent the unit and were here last month but it was still cold and we didn't use it. HELP...we are burning up!
Thanks!

Ok it unit is a central I'm suspecting a voltage transformer is defective you see these units need 24v to turn on certain components but if your air handler turns on, your getting 24v to the fan relay, the problem would be elsewhere. if your handy with a volt meter open the thermostat(if applicable) put the meter on ac volts and measure to see if there's 24v between the R and Y terminals

if so your cooling contactor is defective. (If you get 24 v and unit outside dosen't turn on) if there isn't some fuse on the air handler control board blew out.

you can e-mail me @ hvac.tech7872pr@gmail.com if you need more info

How do i deal with the dripping of water from my Mitsubiishi split system from inside unit? Will putting the unit on 19 and then turning it full bore clear over condensing?


NO
the water is condensation from the humidity in the air turning to water on the cold evaporator core
normally it drips into a tray and drains away outside
if it is inside ( running down the walls it indicates
the drain hole and tube is blocked or the evaporator core is covered in gunk and holding the water up and not dripping where it is designed to
Call an accredited ac specialist shop to clean the fins and drain tube

Why does my home A/C unit result in a constant stream of water coming out of the overflow drain? I've had the same unit for 5 years, and it seems that it drains water in ever-increasing amounts. Als


Sounds like it is freezing up. Kind of hard to say since you did not say whether it is a central heat and air system. My overflow was constantly draining onto my patio from overflow. I crawled up in the attic and followed the pvc pipe where it came in from the outside and closer to the central unit in the attic I drilled a hole in the 90 degree elbow of the pvc and unclogged the pipe which was frozen from running so long. Then I covered the hole with silicone. no more leak coming from overflow

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

My deLonghi dehumidifier no longer dehumidifies. The device appears to be functioning OK but is not taking a drop of moisture into the tank. Previously, it filled in about 48 hours.


Hi, Soorry for the delay in the respones but I was stuck in a factory job the last few days.
When this happens usuall either the compressor is not running or the unit is packed with dirt. Can you tell me if you hear the compressor kicking on? I will look up this model and cover all the bases for you. The sysytem is slow on resposnes right now but I will keep on top of this with you till se get it going.

A/c fan not working=thermostat is working(central a/c system)a/c


The fan on the outside unit is powered from it's 240 volt source. Check that the breaker for the outside unit is not tripped. Also, a contactor is inside the outer unit that starts the fan - it may be faulty.
