Describe your Carrier IBM UNIT 2380 79F4796 Drive Case Problem Large pan, beneath unit, fills up and overflows, damaging plaster below during cooling mode. If the unit is working properly, I've been told, this pan should not get any water in it. Thus the problem is inside the unit. What is causing this pan to get water in it?

Blower wont work inside attic

2006 and later models used an X13 non capacitor motor. A high percentage of them have failed. Warranty is 5 years on parts, you pay for service.. A new one cost over $500 plus installation. If your are lucky It could be the condensate line is clogged. The drain pan fills and a float switch turns the unit off to prevent water damage from overflow.

Drain pan overflows weekly - compressor hot to touch model FRT18B5JMO 3 years old

Hi and welcome to FixYa, I am Kelly.

I note that this unit has a rear coil condensor on the back of the freezer and that there is not a cooling fan.

In the drip pan Item 26 of the manual below there is a tube that is item 87 also in the parts manual below on pages 8 (picture) and 9 (part numbers). Make sure the tube 97 is above / resting in the top of the drip pan item 26. That helps evaporate the water.

If your getting lots of ice build up on the evaporator coils each week you need to make sure the freeser door gasket is sealing properly. It should mate to the chassis all the way around the door. Any gaps will cause excess ice build up and more water will be seen during each automatic defrost cycle possibly over-filling the drip pan.

I have a Goodman system and I have water leaking from the the small box next to my furnace. I have what looks like 3 lines running from unit to this box. One is a small copper one, another is a line...

the clear plastic hose is the condensate drain .. indeed they clog frequently .. lthat will allow water to overflow the pan that is desined to capture condensed water from the evaporator.. the plastic hose and the pipe it is attached to need to be cleaned out periodically ... allowing water to overflow can damage other things so its important to get the drain cleared .. however that drain has little to do with cooling efficiency .. your lack of cooling performance could be another problem ... sometimes the evaporator coil gets clogged (large finned unit behind where the overflow hose is attached inside furnace) .. that has to be cleaned once in a while but is tricky to do ... how often depends on how good the furnace air filter is and how often its changed ... as the evaporator becomes clogged with dust the cooling efficiency goes down .. same with the outdoor unit ... you have to wash out leaves and such periodically from the condenser coils .... if every thing is clean but the cooling efficiency is still low then have the unit checked for refrigerrant pressure .. it could be low .. of course make sure the furnace filter is not clogged ... also for cooling make sure all of the registers are open ... closing some can reduce overall efficiency ... make sure the outdoor unit fan is working properly ..

I am seeing a small amount of transmission fluid under my 2003 jeep liberty. what could be causing this?

A loose drain plug in the transmission pan, a loose bolt in the pan, a bad gasket. It could be coming from the power steering as well. Check the resevoir and hoses.

I have a unit in the attic that is installed in the attic horizontally. The condensation leaks out the unit into the overflow pan. I have had the drip pan replaced as it was cracked, the overflow line...

It sounds like to me that the leak is coming from inside the unit(air handler) possibly your evaporator coil is icing up and causing a build up of water just below where the 3/4" P.V.C. drain line connects. Instead of draining out the line, it is finding its way out of the unit else where. I have seen this many times. It sounds like you have done everything that I would have done, but take a look at the bottom of the evaporator pan and I bet that it also is starting to rust out.If the new overflow pan is not leaking, and the condensate line is leak free, it has to be leaking from the evap pan inside the unit.That's why you have the overflow pan in the 1st place to prevent ceiling damage as I am sure you know. I hope I have been of some help to you, please let me know what you find.

Sincerely, Shastalaker7

How do I put oil in for 4 wheel drive, how and where can I buy

On the rear of the transfer case you will see two large nuts. one slightly higher than the other, both about 1" wrench size (may be slightly larger)
Remove the top one while vehicle is on level ground, and fill from there. Put a pan below it to catch any overflow. Unit is full when fluid begins to run out of the hole. Once finished, your'e a mechanic!!!
Good Luck!!

Panel lit and motor running but will not cylce

It's almost certainly the case that something has started leaking in the bottom of the dishwasher (a seal or hose) and has filled the bottom catch pan with water. There is a float in the pan which will trip the unit into a mode where the pump turns on to flush out all the water inside the unit to avoid overflowing the pan and causing much more damage (to the subfloor and anything on lower stories or basement). As long as you have the unit turned on, the pump will run to flush out water. Until the catch pan is purged or enough water dries up.
At any rate, somebody needs to look at why the catch pan is filling up with water.

Pan that catches water under freezer side overflows

That is pretty unusual unless you live in a humid area. Some units have a switch that allows you to adjust for this and it simply defrosts every 12 instead of 24 hours. Also, the fan that cools the coils under the unit may not be running at normal speed since the warmth of the coils and the fan generally suffice to return the accumulated water into the air. You are right to check the door seals since if these are no longer seating well, external humidity will be gathered by the cooling coils and subsequently become the water collected below that is plaguing you.

A.C. unit

One of the cause of water dripping in the indoor is restricted drainage. To Identify if your drainage is restricted.
- Turn "off " the circuit breaker and take out the face cover of the unit.
- Turn "on" the circuit breaker and start the unit, wait until the unit drips.
- When the unit dripped check the drain pan if overflowed with water.
- If the drain pan is full of water you need to flush the drainage with water to remove the restriction. If the pressure of water in your area is high you can use your garden hose to flush the drainage.

Another is dirty evaporator fins (icing), dirty drain pan, broken drain pan or incorrect installation.
