Top 20 Intertherm P3RA-060K Air Conditioner Questions & Answers

wire too small, breaker too small, loose connection, over amperage If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

The tube is gas supply for pilot. You have to make sure the thermocouple is in the flame at least half way and make sure its tight in the gas valve. There should be a small silver plug on the gas valve near the pilot supply tube. You can pop the cap and adjust the height of the pilot flame a little. Can you tell if it has a flame rod in or above the flame? If it does You can remove it and clean it with steel wool.

If the capacitor is wired wrong you may have tripped the braker or blown a fuse.

If nothing works,no display on the thermostat,no fan only,it is bad.
OR
You can test the input and output with a voltmeter.
240 volts in 24 volts out.

Hi, if the unit had a leak in it, was the leak located and repaired? Did he check the pressures in the unit now? If it switches to the aux mode ( Heat Strips ) is normally caused when your primary unit, compressor and freon are low on charge. I would have that checked.

Replace indoor room sensor.

some times heat pumps have a fan cycling switch to keep the head pressure normal in cool weather or check the defrost relay for the fan when a heat pump condenser gets frosted it will stop the fan and reverse into cooling mode for a few min. to melt the ice and this function is done by a relay or a printed circuit board if it goes bad you wont have voltage to the fan

it sounds like your superheat needs to be calibrated or you have a small leak but it could be something as little as needing to clean your coils this will cause that and more when air cant get across them

The buzzing noise is probably the fan motor. Is the compressor running? First make sure that there are no tripped breakers. After that kill the power and check the capacitor with a multimeter. If that checks good then check the fan motor windings with the multimeter. Let me know if you have any questions.

Check the voltage at the contactor where the 24 vac connects to the coil for the contactor so you can see if it is making it that far. It will be 2 smaller wires that are not connected to the 240 vac. Let me know if you have 24 vac there. The thermostat will have to be calling for air for the 24 vac to be present. let me know what you find.

Isolate the secondary side of the transformer and then check the voltage. If less than 21 volts, change it. Don't be surprized if a good transformer gives you 26 to 27 volts.

OUTSIDE FAN OR INSIDE FAN OR BOTH. IF BOTH CHECK THERMOSTAT WIRE HOOK UP. IF YOU INSTALLED NEW TSTAT CHECK FOR JUMPER ON RH-RC TERMINALS ON TSTAT BACK PLATE. IF INSIDE FAN COMES ON WITH FAN IN ON SETTING AT FAN ON AUTO LEVER THAN PROBLEM IS AT OUTSIDE UNIT. CHECK FUSES IN BOX ON OUTSIDE WALL. SHUT OFF BREAKER FIRST.

This sounds like a service call..918-6878813- or 9183609272.

Check the voltage to the contactor coil, it will do that if the voltage is low. This is the 24 volt part.

If its the P3RA-060K then you would have a 5 ton unit there

Sounds to me like the run capacitor is bad. It is a dual one which means runs the fan and the compressor. No big deal capacitors are only 10 bucks and easy to replace.

First turn off the electricity to unit at breaker would be best. Next after you open the access panel locate the capacitor and make a note which wires go where one side is marked fan the other is herm. in the middle is comm. Take the old one in and get a new one same size and reinstall. Now parts only have one year warranty but they should have a discount on a person that bought a unit from them if you talk to them and tell them how can this happen only 2 years old. you know the story they might just throw one in for free to keep good business practice. Let me know how it goes. ken

compressor may not be running or low on freon

Thanks for your Question,
A question or two for you, when your husband was hooking up the new stat, could he have inadvertently touched the low voltage wires together ? if so have you checked the circuit board at the furnace to see if the fuse is blown ? The fuse looks like a automotive fuse on the board, look carefully sometimes its a little hard to find it, take the fuse out and look at it, you can tell if its burned out, I would almost be certain that this is where your problem is at, replace the fuse with another 3amp fuse, make sure the power is off before doing this, and with the power off hook in your new t-stat, bet it will work for ya ! Or hook back up the old one, in any case you seem to have a power issue, hope this was of help, thanks again for your question,
mr.grzz

I am assuming this is a heat pump? (Typical when the t-stat has a green light.).

Please confirm

If a heat pump, is the outdoor unit frozen up? There can be some frosting, but it should not be a block of ice.

If there is an emergency heat switch on the t-stat, can you flip that to emergency heat? Do you get heat then?

Pleas advise and I can help you troubleshoot this problem further.

There are shut off valves under the brass caps by the ports uses hex wrench.
