Question about Ruud UAMB Air Conditioner

1 Answer

I have a RUUD gas pack unit.....when you turn on the heat, the blower does not blow any air out of the vents while on "auto". If you put it on "on" it blows cold air out of the vents. What is wrong?

Sounds like the thermostat is hooked up wrong. If the ac doesnt work right its in the thermostat programming or the wiring. Hope this helps good luck

SOURCE: RUUD model URGG-10E31JKR GASS PACK purge fan and main blower

if the purge fan wont start on its own see if there is a capactor attached. if not replace it. more than likely you cannot lube the bearings in your blower motor. the new fans are not serviceable.

SOURCE: Daily reset of outside unit

I have the same unit and was having the same problem. My brother works on A/C's and told me that the coils most likely needed cleaning from the inside out because when they are clogged with a lot of debris the system will overheat and cause that switch to trip and so far it has worked. What you need to do is turn the main breaker off to the outside unit first then take the four screws out of the top of the unit, use a flat head screwdriver and lift the fan it's self up out of the carefully taking caution of the wires going to the fan, then take the garden hose with a spray nozzle and wash the coils from the inside spraying through the coil to the outside and then wash the louvers off of all the debris and this should help.

SOURCE: uotside unit blowing cool air but hot on the inside

It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.

SOURCE: Not blowing cool air on my Ruud, 18 years old, outside unit.

If you have ice on the Line you are iced up. If coil is iced no air can get thru. Now First. Turn of ac and turn fan to on posotion. That will thaw unit. Let it run 45 minutes. That should do it. If the fan is not running you amy have a bad fan relay. One of the reason iced up unit is dirty evap, coil inside. Try to thaw it out first. You can clean the coil with a stool brush. Does not damage the coils. Good luck

Unit turns on but doesn't stay on


If you have a non digital type of thermostat and a gas furnace, it will have an adjustable anticipater as part of the thermostat. In a normally operating system the average anticipater setting is 0.4 amps. Or simply .4 . Incorrect setting can cause the heat to turn off early or late.

If the burners are staying on but the blower turns off you could have a faulty blower motor. Sometimes replacing a faulty blower motor run capacitor will extend the operational life of the motor.

There a many other possibilities.

You didn't mention if you checked for 115 volts at the power supply to the air handler. The unit outside has its own power supply. A lot of times the switch that is on the wall doesn't like to work after its been turned off and back on for service, also check the blower door safety switch. If the blower door hasn't been put back in place properly and snugly it will kill power to the whole air handler. Hope this helps. Good luck

When you set the the switch to ON, I'm assuming that is the fan control? You should leave that on AUTO. The furnace will turn the fan on when the heat exchanger reaches a preset temperature. Which will prevent COLD air from coming out of your vents.

Turned on a/c unit no air blowing from vents. unit is on out side runing


2 things could be the problem 1 The blower motor capacitor has one out. This is a small oval or round piece that the wiring to the blower motor is attached if this is out the blower motor will not work. 2nd. the blower motor itself has burnt out. Replace the capacitor and the motor together should you have to change out the motor. Good luck hope this helps

Hello

Okay did you check your thermostat to see if you have the fan switch on auto? The switch must be on auto or the fan will continue to run. If the thermostat fan switch is on auto then there is a malfunction in the thermostat probably. You can go to your forced air unit and on unplug the unit. That way it will not turn on at all, because the forced air unit is controlled by the thermostat. Hope this helps.
