SOURCE: thermoking

This system uses in conjunction with the transformers a rectifier which converts the High AC current voltage (220V-AC) to a Low AC current voltage (12V-AC) and then the rectifier converts that energy into the D/C current (12V DC). The two diffrent 12V power sources are controlled, operated by a "electric" relay, via a roadside or electric selector switch. DS_TK TECH

SOURCE: AC Control Transformer keeps failing.

well it has blown the fuse on the transformer, then you have coil switch bad.It could be the coil on the contath in for cooling.But can check by taking the yellow wire a loose and see if the don't blow. The red wire is one side of the transformer and the com could be any color.But look at the red wire because it is the main wire that travel the voltage throuhg the unit.

SOURCE: Instructions manual seems to imply that two 24 Vac

Hi,
No, you do not need another one. Wire everything just as you see it in the wiring schematics and you will only need the transformer supplied with the unit.

I would contact Sherwood as Transformers are deemed to be safety components and should be replaced with excat parts or those recommended by the maker.

SOURCE: Why two 24 Vac on aprilaire 700's control unit?

Okay, I looked up the installation manual online to see exactly what you are working with.
Yes the R anc C need to be hooked to the transformer supplied with the unit. The primary 120v side needs to be hooked into the power coming into the furnace. this can easily be done were the L and N get hooked into your furnace or circuit board on the furnace. This will provide the contiuous power to the unit. Preferably you will hook this after the door switch of the furnace so that you will kill the power toit if you take the blower door off.
The ODT terminals are for the outdoor sensor if you want to hook that up it will vary the humidiy in your home according to the outdoor temperature then.
Now the W/G and Cf terminals. If you have 24v coming from the HUM terminals of your furnace you DO NOT need a second transformer. You must check your furnace manual or check the voltage to them with the furnace blower energized. The HUM terminals will only have power to them when the blower should be running.
If the HUM terminals are 120v then you need to get another transformer and hook up the primary side to the HUM terminals so it is powered only when the the blower is running. Hook the secondary side to the W/G and Cf terminals.
So bottom line is that you need to figure out what voltage your furnace is giving to the HUM terminals and then go from there. Some times the EAC terminals or the ACC terminals will be 24v on the furnace board. Either of them could be used also, as they are only energized when the blower is running also.

Sony cfd-s01 boombox radio


Hi Bart,
You will find there is a specification plate on the rear of the unit.
It should have a rating on it showing the wattage of the unit. This is usually the amount needed to operate all the functions of the boombox.
The wattage is your input voltage multiplied by the current draw in amps. So the amperage is the rated wattage of the unit divided by the input voltage.
Usually all power goes through the transformer, so I would use this input amperage as a guide, and assuming there is no power loss, use the same calculation for the output - you know it is 9 volts, so the wattage going to the unit is the same as the input wattage, so you can calculate the amperage from this.
Transformers usually work on AC input/output, so there will also be a rectifier to convert the AC to DC for your boombox.
I would add 10 - 20% above your calculation to make sure you have sufficient power. Also I suggest that you install a fuse between your transformer and the boombox for safety.

Where to thw wires go


Output wires (going to lights) connect to different terminals depending on desired output voltage.
For example 12 volt, 13 volt or 15 volt.
Input wires (coming from power source) depend on specific timer. Some timers plug into outlet, while other are hardwired.
Copy following link for some example Kitchler transformer wiring.

How to identify the matching transformer terminal by means of terminal resistance? and which terminals is for input or output?


Doing a resistance test on a transformer will not give the information you require as you will read very little, if any resistance. What you need to do is an impedance check and that gets involved. If it is a normally wound transformer, not an auto transformer, you can isolate which is the primary and the secondary windings. Unless the transformer is a multi voltage input unit, the primary side will have continuity through only two terminals. The secondary could be more than two if it is a multi output voltage one. If the transformer is a step down, the primary windings will be the thinner wired windings and vice-versa. To actually test the transformer, get hold of a transformer with about a 20 vac output and try it across the two terminals you have identified as the primary windings, you should ge a proportional voltage of the actual output. eg. with 20 vac input and a 2 vac reading at the secondary, the actual output would be 11 vac if your mains voltage is 110 volts. Take care that you are using the transformer at the voltage it is designed for, otherwise it will overheat and burn out.

I have a Samsung microwave model SMH7177STE/BE. Will only heat a few minutes before and shut off, now there is no heat. I am a licensed elect. but no experience with microwaves and having difficulty...


Its tripping a high limit most likely. Be careful there is 2100 to 4000 volt high side with a capacitor if its not an inverter. The standard components consist of noise board, fuse, touch panel and power controller, high limits, door switches, whipper motor, fan, transformer, capacitor, transformer, magnetron, diode, plate rotator.
Discharge cap (for safety and further testing).. Test fuse; if fuse tests blown test door switches first. Test limits. Check amp draw with slow blow fuse; open door to stop unit and again discharge capacitor. Test resistance to ground on whipper, fan, magnetron, light. Test resistance lead to lead (measurable on motors/coils/magnetron). Test capacitor in ferrads, compare to spec on print. Check diode forward and reverse. Test output voltage from power control board to transformer. Test transformer coils.
Best of luck and play safe; dont test voltage output from the transformer, voltage at capacitor or magnetron.

My RCA RS2620 has a shorted D820 and a burned R886. Can anyone recomend replacements / know the value of R 886 or have a schematic of this unit?


hi rnollett,

I just plugged my cousins RCA RS2620 into 220volt mains and burned the transformer because its originally 110 volt rating from canada. If you could please test your units transformer output voltages of RED-BLACK-RED wires so I can tell the technician to rewind the transformer usable to 220volt mains, he is asking me those output voltages and I dont have a clue.
Regarding your D820 and R886 if you have'nt yet found suitable replacements, in return, I will check the values of those parts here and I will send it to you.
Many thanks in advance.

No output voltage on circuit board terminals 1,2,3,and 4.


I think those are your thermostat connections and are probably 24 vac. Check the output of the transformer and make sure it is 24 vac. If it isn't make sure power is supplied to the input of the transformer.

After replacing my Run and Start capacitors at the advise of this website, the problem continues. The compressor chatters loudly, then the fan comes on and the chatter stops. The unit is a RUUD Heat Pump...


If I were there I would do a pressure check on the system.
Then a locked rotor amp draw on the compressor.
Then a amp draw on the fan motor.
I would compare these figures to the specs on the service plate and look for a variance.
I would also thoroughly visually inspect the contactor for loose connections and pits or burns on the points.
I would remove the wire terminal cover on the compressor and check the wires and terminals for burns ,loose, or corrosion.
I would also do a mfd check on the replacement capacitor to make sure it is correct as well as capacitor voltage rating at 370 or 440 volts.
If all checked out OK I would add a start assist capacitor to the S/R capacitor.
If all this fails your compressor may be developing bad valves.

Power problem the transformer burn out can you help me?


it's probably a 12 volt center tapped a/c transformer,you could look on old unit transformer and see if this is the voltage output, then go to any electronics parts store and get a repl trandformer rated at 12v.a.c. and is center tapped at least 1 amp cuuent output

CARRIER AIR CONDITIONER/HEAT PUMP PROBLEM WOULD NOT RESPOND TO THERMOSTAT. UNIT IS AT LAKE HOUSE WHERE WE DO HAVE BAD STORMS. IN CHECKING, INSIDE PART OF UNIT HAD BURNED UP THE TRANSFORMER BUT NOT...


what I have always been told is if your 24 volt side burns out check the high volt side if the hi volt side burns out check the low volt side.

A quick way if the primary side is burningout due to a problem with the low volt side:
1 MArk all the thermostat wires at the indoor unit
2 Disconnect them at the indoor unit.
3 Check main line voltage before proceeding (A 208 volt is not considered 220V and 240v Is not considered 208V> In these circumstances the voltage may have changed with the power company replacing a transformer and now you need to change the main power input lines at your control transformer for the correct operating voltage). If okj then proceed:

4 If you have an amp meter attach it to one of the lines going to the transformer.
5 Apply main power and listen for hum, note if smell starts again and if so problem has to be in board or main incoming voltage too high or too low. Amp draw should be less than 3 amps.
6 If your to this point and still havent found any trouble in the above as of yet, Connect the wire marked "C" together. Then just touch the thermostat wires one at a time to the places where they go on the indoor unit and watch the amp meter. If you donmt see the meter jump the circut is probably ok but leave them disconnected until you touch all of them to the correct place or wire. Here is a possible problem I ahve seen a thermostat wireing problem if the wires are stripped too far and a "whisker" of the wire sticks out and allowes one of the other wires to cross short out. In this case just cut off the excess wire or bend it over out of the way asnd continue with the test. You can always cut it off later after the tests. If you see the meter jump up and stay up and /or blowes the fuse the wire that you used and it blew is where to consentrate.
7 No wiring problem found means that you could have a relay or contactor not pulling in properly.
and this will cause the amp draw to go way over the transformers power out put or VA rating.
8 Inspect the thermostat wiring for the "whisker" I mentioned above.
9 If you have done this to the end of the thermostat wires and your main incomming voltage is correctly wired in on the transformer andf your relays and contactors are pulling in evenly and not delaying excessively your problem should be fixed.

If this helps you please rate me as high as you can and thank you for using fixya.

Marantz mm9000 has died


The main power transformer may not have the correct voltages coming out of it. I would check the output volts at the terminals. I would also check the out puts from the solenoids.
