My outdoor unit will not turn on at all in heat mode but works fine in cool.
I have a Goodman split system Heat pump model CPKJ24-18 with a Ruud Oil furnace as Aux Heat controlled by a Honeywell Heat Pump Tstat model CT70A.
We bought our first house in March. Im almost sure that the system worked then.
I am an electrician's helper and am comfortable working with electricity and troubleshooting. If someone could point me in the right direction I think I ll be ok. Thank you for you help, we really cant afford to call anyone and burning oil is expensive

Thanks

 

Does anything happens when you first turn the heat pump on? (Fans running?)

Here is a link to your stat. Double check to make sure all wires are hooked up right.

I dont know how cold it is there now . But can the outdoor tstat have it turned over to the oil furnace and it not come on. Id look out there to see what has it off.

is the oil heat working?

 

The temperature is fine (45F), the Outdoor thermostat is good. And I think the indoor tstat is wired right but i may be wrong.
X-Blue

G-Green
Y1-Yellow
W1-White

The Indoor Tstat is wired to a board mounted on the outside of the furnace that says Duel Fuel on it. It has 2 Relays and 3 terminal Blocks they are labled and wired

Thanks for all the replys

Oh yeah. the Furnace runs whenever the Thermostat calls for heat. But the outdoor unit doesnt make a sound

 

Can someone tell me what signals the outdoor unit should be getting in heat mode. Im not sure about the orange Yellow and White wires

OD- Brown outdoor tstat
SA-Black outdoor tstat
O-Orange (thats the cooling control right?) should that be off?
Y-Yellow (Compressor) Should that be on or off?
W-White I dont think thats hooked to anything
R-Red +24
C-Blue Ground

Any help you all can give would be great

Im thinking the Themostat is wired wrong my theory is that Y and W1 should be jumped and that the white wire should be moved to W2 im not sure.
Do i run the risk of breaking anything messing around with the wires? My 24volt transformer is Fused.

Thanks alot

 

Look at the back side of the unit's cover and see if the O is for heat or cool.. Diffrent unit do it diffrent.

If the O is for heat, You should read power to that and Y to run the compressor.

What the brand/model # is your control board that does the switch over?

From what I can see, everything is wired right.

 

Im lost here.
You show X on the tstat has blue on the first one.
Then you say tstat again and show
the blue on the C common?????

Where the outdoor tstat is set at that is the temp that will turn the heatpump off and the oil burner on. Can you find what it is set for . Might help

ED

 

Ed.

X on stat itself is common,

The next section he was talking about is the switch over control is where the all the wires are tied up to. and that is C - Common

 

I got it. The thermostat was wired wrong. The way it was wired as soon as the tstat called for heat (W) the signal was sent to the furnace. Y was never activated in heat mode on the outdoor unit.
now when the tstat calls for heat less than 2 degrees off it activates the heat pump more than 2 degrees it calls for the furnace (W2)
I hooked it up and it works. The outdoor unit is working and the house is getting warmer.
To answer you questions The outdoor Tstat was set to 32F, I put it in the freezer to test it. Orange is cool. And my Switchover says Duel Fuel which is trademarked so i guess thats the brand or model. If anyone knew a website with literature on it I would definately like to have it for future use.

Thank you all so much for you help. You really got me thinking in the right direction. You all saved us a lot of money, time and Oil

You like to play. You can try and set the out door tstat say down to 30o to start and see if it will keep the house warm for you on just the heat pump. If it will try lower. Can save on oil.

ED

 

Cool, thanks for the tip. I was curious about that. I will give it a try

 

There might be a thermostat called a bonnet thermostat near the indoor coil. This is installed to keep the heat pump from building up too much pressure and exploding refrigerant gas if the oil furnace and the heat pump come on at the same time. The controls that you have is a nice way to do things but you need to know how to set it up right. That would require knowing things like balance points for your area and that perticular heat pump.
