Help with Goodman ARUF049 air handler?

I need help..my ex had replaced my oil furnace with a Goodman ARUF049 air handler or so the sticker outside the unit says. When we broke up he took the furnace and everything including the thermostat. So needless to say after many arguments he just brought back the unit. I went to put it in...bought a new thermostat...and new thermostat wire. I connected the RH..the W...and the G wires from the thermostat to the furnace. Now when I put the fan switch to on ...the blower runs....however, it doesnt run any other time....on auto....anything with heat.....I dont have airconditioning....and am just using it to heat the home. I can not find any information on this unit anywhere....any help would be appreciated. I do plan on calling a HVAC/heating guy tomorrow....just wanted to see if I was doing something wrong.

Thanks

R is 24volts from unit, W is heat, G is fan, Y is cool, C is common. Normally Rc/Rh is connected by a factory jumper in the tstat. And you connect R to either one(rc/rh). We usually use the same colors per terminal letters. Such as R=red, W=white, G=green, Y=yellow, and C= blue. Not all units are wired this way. Not sure how it is wired at the inside unit so this may not help. But this is a common way to wire them. And the C terminal is not necessary if you want to use batteries in the tstat. Hope this helps!

Read the manual of the stat. In settings you will find an option that will let you set to where the THERMOSTAT CONTROLS THE FAN. This is what you want. Good Luck

Witch blower is running, the inducer or the systems blower?
System blower could mean the the high limit is opening and shutting down the systems gas train, I would check this out first.

The other problem could be with the pressure switch for the gas train, it is supplied from the inducer motor, check to see if it is operating fully.

HSI boards do go from time to time, this sounds more like a system control problem.

SOURCE: Ruud furnace Model URKA A030jK08 Code opt 589

sounds like the circuit running to your condenser powers your furnace. when u disconnect power to the furnace it will reset and run the blower on startup. check the tube connecting the vacuum switch to the induced draft motor. maybe a leak. good luck

SOURCE: Ihave a goodman GMPN furnace. The blower will not

Maybe not! there is a limit switch that has opened not allowing power to pass and start the furnace. You will need to tale a Ohm meter and follow the wires thru any safety switch. In your case, it may be the thermo-disc near or over the burner box. Jump it out to test it. Now why is your blower not working (which could have been the reason why the thermo-disc opened)? Once you find which safety switch is open and you have jumped it out, take a jumper wire and jump between the R and G terminals on the circuit board. This should start your fan. If not, either the fan is stuck, the fan motor is bad or hopefully noy; the circuit board is bad.

You need to check to see if the voltage is coming to pull the contact in, if not then you will have to check for the voltage at the air handler/furnace on the main board for the voltage. If the voltage is at the contactor then the coil is bad and you need to purchase a new one. All the information is on the old one on the top or bottom. Hope this helps tim

I don't see any reason to change the furnace unless it's an air handler and not a furnace with a coil on top or bottom. And then, the only reason to change the inside unit when you change the outside unit is because it's a R-22 system and your going back with a 410A system. They just discontinued R-22 equipment this year and not a lot are still available. But even if that's the case, the only thing they should have to replace is the coil and maybe the copper line set. That's all I can think of. Hope this helps!

I have a T3BA-036KA the outside unit will not


You need 24 volts going to the coil of the contactor. If you do not have 24 volts, you will need to trace the wiring back to see where you are losing it from. Try placing your voltmeter at C & Y coming from your air handler. If not, go to your air handler and test for 24 volts ac at C & Y coming from your thermostat. If you do not have 24 volts coming from your thermostat, there is either a problem with the thermostat or there is a problem with the wiring between the thermostat and the air handler. If you have 24 volts at the air handler coming from the thermostat but you do not have 24 volts at the outdoor unit coming from the air handler, then you have a problem with the wires between the air handler and the outdoor unit.

I hope you find this information to be very helpful to you moving forward. Please leave a rating. :-)

I have a Goodman electric furnace model ARUF049-00A-1. It seems to run constantly and emits an odor of sewer through the air ducts


Can you view inside to the electic heaters and ensure they are clean? On rare occasions, insulation from furnace or attic believe it or not gets into furnace and gets cought up in the coils. It could possibly ruin your sequencers, you'll have to have a tech replace those.

Need line set size for goodman ck-36-1a


If your running gas heat it's 5/8 3/8 tubing.If it's elec. heat it's 3/4 3/8 tubing. Etheirway 3/4 3/8 works for both. Use 6 wire for tstat from tstat to furnace or air handler, and you need is 2 wire from condensing unit [outside] to furnace or air handler or anything more than two.
