  1. Mr. Arnold,Have a Rheem model RAKA-024JAZ serial #5882/M1100/21908. A.C. condenser fan not running,compressor runs & sounds good until it heats up,with a Guess? I replaced the capacitor with a duel titan ,but this did not cure problem,but the $19.00 was cheap compared to the $400.00 Reids charged me a few years ago,so a extra capacitor will be good to have on hand. So i’m thinking the contactor or the condenser fan motor is the problem? What do you think sir?

    1. Hi Keith! It you are getting 220 to 245 volts AC between L1 and L2 (Power wires coming from your disconnect box) on the contactor and when the contactor is energized getting 220 to 245 volts between T1 and T2 then the contactor is OK. I would suggest that you trace down the two wires that power the fan motor and see if you are getting 220 to 245 volts AC to the fan motor when the unit is turned on. Please be careful when working with high voltage electricity. If you are getting 220 to 245 volts to the fan motor and the motor is not running then you probably need a new fan motor. Our Rheem, Ruud parts program shows that your unit uses fan motor part number: 51-23055-11 which we sell on the following page: I hope you can easily find and fix the problem. Steve

      1. Thank’s Steve! Checked as you suggested,good voltage on everything( including the motor when energized.Noticed the replacement motor has 6 wires to my motor with 3 black, brown, & orange??Does the replacement motor have a diagram or better (instructions for idiots)LOL! also will my new duel titan pro#25/5mfd370440 capacitor be compatible? Also since the contactor is not expensive ,could you give me the part number please and i’ll order this also as a backup .Thank’s again Brother!

      2. Hi! All motors come with a wiring diagram on the label of the motor. Motors do not come with instructions but we have a good video on this subject on the following page: I searched our database and did not see which motor you purchased from us? I see where you purchased the 25/5 mfd Titan Pro Capacitor, but not a motor. If the motor that you purchased uses a 5 MFD capacitor then the 25/5 MFD Titan Pro Capacitor would work well. If you would like for me to look up the contactor part number please send me your units model number and if you have a Bryant Carrier unit I will need the product number. Please send this information to our email address: It would be best to communicate using our email. I hope you have a great day! Steve

  2. An electrician friend said the capacitor on my heat pump was bad and needed to be replaced. He got one and last night at 15 degrees when I turned it on, it blew the circuit breaker. Now he’s saying it’s the compressor. I think he’s fishing b/c he never came back to check anything. I’m very suspicious of his hit & miss diagnosis and don’t want to spend a fortune replacing parts. I’m also on a fixed income due to a disability.

    1. So sorry to hear that you heat pump is not working. If it is staying at 20 degrees or below outside for long periods of time I would suggest turning your system to emergency heat. You electrician friend could be right. I have seen compressors fail shortly after replacing a bad capacitor. Your electrician could have done a test to see if the compressor is actually bad. We discuss this in a post on the following page: I would suggest the you get another opinion by a licensed HVAC company if you are skeptical of the electrician. Most of the time when the breaker blows on heat pump start up it is the compressor grounding out and you will need a new compressor or a new heat pump system. I hope you can get it fixed soon! Steve

    1. Hi Mr. Lange!
      Sorry you did not get my email earlier this morning. Here is a copy of the email I wrote to you about 8 AM this morning:
      Dear Mr. Lange!
      I am terribly sorry, but I called both of my suppliers so I could pick up the two wire pilot burner and they do not have it in stock. I have canceled your order and refunded your PayPal account in full. I hope you can find it on another site. I copied the transaction details which show the refund below. So very sorry!

  4. Having problem with my Carrier Furnace, Draft inducer motor not working, Tape the blower door safety switch shut (if equipped) and set your thermostat so it is calling for heat. Use a volt meter set to “Volts AC” and test between terminals W (usually white wire) and C (Com) getting, 25.6 volts between these two terminals. AC between the R (red) and C (com) getting, 26.8. Check the fuse it looks good.

    I start the furnace and the Fan blower starts but the draft inducer does not and continue to blow cool air no fire, LED blink continous on and off.
    Now what do i need to do next.

    1. Hi! The voltages that you tested between W and C and R and C are normal when the furnace is calling for heat. It sounds like you either have a control board problem where the relay on the control board is not sending voltage to the draft inducer or you have a draft inducer problem. I would suggest checking the voltage that goes to the draft inducer. If you are getting 110 volts to the inducer motor and it is not working then your have a draft inducer motor problem. If you aren’t getting voltage to the draft inducer then you need a control board. It is normal for the furnace fan to run for a couple of minutes when the furnace is powered up from the power switch. If you would like for me to look up part then please send your furnace product number to our email address and I will be glad to look up parts. I hope you can easily find and fix the problem. Steve

      1. Steve,
        I’m only getting 25 volts AC, the wires that connected to the draft inducer .
        My PC board, P/N 1012-940-J HK42FZ009.

      2. Hi! If you are only getting 24 volts to the draft inducer when the thermostat is calling for heat then you probably need a new control board. Please make sure that you are getting 24 to 28 Volts AC between the C (com) and W terminals on the control board when your thermostat is calling for heat. The HK42FZ009 control board has been replaced by the 325878-751 conversion kit control board that we sell on the following page: If you aren’t getting voltage to the draft inducer then more than likely the control board is at fault. I hope you can easily find and fix the problem. Steve

      3. Steve,
        Draft Inducer motor is this 110 volts , DC or AC.

      4. The draft inducer on most furnaces are powered by AC voltage. If you have a high efficiency furnace with an ECM draft inducer then it runs on DC. ECM motors are hard to troubleshoot and usually require special equipment for testing the motor. I hope you can easily find and fix your problem. Steve

  5. my rheem 3 ton gaspack will not ignite have replaced gas valve and ignitor getting spark to manifold when unit calls for heat I can light manually unit lights and runs until unit gets to set temperature .wnen thermostat calls for heat it sparks will not ignite can light manually

    1. Hi Mr. Creasy! Sorry to hear you are having trouble with your Rheem gaspack. Since the unit works correctly when you light it manually, then this sounds like to me it would be an issue with the control board not sending power to the PV (Pilot Valve) on you gas valve to light the pilot. The control that sends the power to the gas valve whether it be a control board or another control then this is probably your problem. Just to make sure I would suggest that you check all safety controls like the limit, rollouts and pressure switch to make sure they are closed and you can eliminate these safety controls as the problem. If you need me to look up parts please send your furnace’s model number and serial number to our email address and I will be glad to look up parts. I hope you can easily find and fix the problem. Steve
