The transformer is for the low voltage side of your furnace, you should be able to take the door off of the furnace and follow the wiring schematic on the inside of the door to wire it back correctly.

Amana furnace. How do I replace a 4-wire transformer with a 6-wire?


The new transformer should have a description on the side or top. Like: Com, Color, Volt. For example, say you have `120 volts, com-white, black wire - 120 Volts. Make sure you carefully read which wires to use or have a tech come out.

Havc thermostats


I will assume you did not write down what color wire you took of each letter on old thermostat? Sometimes color of wire doesn't matter as some installers will use whatever color. If you noted where each wire was on old thermostat, just put same color wire to same letter on new one. Under normal situation. y is for compressor (cool) G, is for fan (on AC) , RC is 24 volts from transformer for AC side, RH is 24 volt transformer from heat/furnace, and W is for other wire from furnace, is furnace is only 2 wire system. Was there any wire connected to A on old thermostat?

My parents have a Ruud Acheiver central air unit coupled with the Acheiver furnace (not sure which model but approx 4 years old). Power went out for them after a storm on Monday. When power came back on...


If you held the contactors at the condensor in and the outdoor fan and compressor started, you have a control circuitry problem. The thermostat is more than likely wired incorrectly. The red wire at the t-stat is the 24VAC hot. If you touch it to the green wire the indoor fan should start. If you touch it to the wire that is going to the coil on the contactor you pushed in (color unknown as I am not there) it should fire the compressor and outdoor fan. Thermostats can be very tricky sometimes. Based on what you have written it is definitely a control voltage problem. If you do not have 24VAC you need to check the input power on the transformer and make sure you are getting 24VAC output.

Whatever you do....do not take the red wire on the t stat and arbitrarily connect it to any other wires. One of those wires is the neutral side of the transformer and if you touch the hot red to it you will have a direct short and will need a new transformer.

If this has helped you please give me a rating I can be proud of. Thank you and best of luck.

I hooked up a honeywell HE220A by-pass humidifier and the water is constantly running with the furnace on or off. I wired it the same way the diagram said using the transformer that plugs into an outlet,...


If you have very old furnace, does it have a blower with a belt. If it does it should only have 2 wires going to blower. If it has 2 you should be able to use the transformer you have plugged into wall and splice into 2 wires going to blower. If you have more than 2 wires to blower, you will need to find out which one is used for heat plus use the white one. If you have a voltage sensor you should be able to find it easily.

York furnace coding 9. which is ground or polarity fault. what do i look for?


I put a new control board in my York today and it was a different/newer board. I immediately had the 9 code thrown at me for grounding and polarity issue. All I had to do was switch the 2 gray wires on the transformer. The gray wires go the the 12 pin connector. The new board is wired differently.

Amana Air Command 80, 20 years old. Electronic ignition. Furnace does not start. Good power to furnace. Themostat properly set. Where do I start looking? Bob


Hello Bob,
Welcome to fixya,

You said, Amana Air Command 80, 20 years old.
Electronic ignition.
Furnace does not start.
Good power to furnace.
Thermostat properly set.
Where do I start looking?

Sounds like you possibly have one or more bad jets if the unit is a gas furnace!
Let me know how it goes.
Huuum

WOW, listen to this story!
I understand you are looking for the solution to fix your furnace your self.
But I want to tell you my story about my smart wife and our furnace.
When we moved into this house the furnace was 20 years old and she suggested that we put a new one that it will save us money.
I laughed at her and replied if it's not broken why fix it!
Six years later it finally broke down and I replaced the whole furnace and central air unit with a new one.
Our utility bill went down $100 dollars a month!
That's $7200. that I lost over 6 years due to not respecting my wife's power of reasoning!
If you can afford it or can get financing replace any unit 20 years old and it will pay for it self.
Can you imaging $1200. a year for 20 years is $24,000 dollars I'm saving with a new and efficient unit.
Do the math!!!!!!!!!

Thank You,
Huuum, Hope I gave you some good fatherly advice.
Please remember to leave a rating
