    I learned an amazing amount of information with respect to the heat pump operation and circuitry in just 15 minutes. Your explanations are perfect. Thanks so much. A little bit of information can sometimes be dangerous. I have a greater amount of confidence now when I am troubleshooting my home system. Many thanks Mike for a wealth of valuable information.

    Hi Sir, i have questions more please. If the heat pump systems (as stated @12:10), "as a whole, only turns on heat-strips and the air handler in 3 circumstances", Then, does this means that, if, a thermostat that is IN THE HEAT MODE, does not activate the FIRST stage heat, (which is the turning on of the outdoor HEAT PUMP unit), but, TURNS ON the INDOOR (air handler unit), the air that the indoor unit BLOWS OUT, is NOT heated AIR? Or put another way. Does the THERMOSTAT in the heat mode, automatically goes the 2nd STAGE of heating, if the first stage is malfunctioning? Or does it just turns ON ONLY THE FAN, (and not the heat strips).
    I am sorry to be asking all these questions, but it just that I have this issue, and I would like know, what is really happening, cause been retired, on a fix income, I dont want to get a shock when i see my electric bill. Thanks again.

    • @JerseyMikeHVAC
      @JerseyMikeHVAC  11 месяцев назад

      Normally heat pump comes on first. Heat strips will only come in if heat pump alone cannot meet set point temp (heat pump requires help) or if room temp and set point have a large difference between them (5 or 6+ degrees).
      Heat strips also come on in heat pump defrost mode. Blower should only run when either heat pump or heat strips are activated, or for a minute or so after shut down when set point temp is met.
      If heat strips come on immediately, then either there is a large differential between room temp and thermostat set point, the heat pump is malfunctioning or emergency heat mode is turned on manually.

      thank you for taking the time to answer, i really appreciate you. I will have it checked out, but it just that in the area i am at in Orlando, the techs it seem HERE, are only interested in replacing units. And it is mostly because they lack the knowledge of the heat pump system and operation. But i will get it fixed. Thnx again.@@JerseyMikeHVAC

      Gday Mike. My Rheem heat pump DEROST BOARD, has two small red indicators on it, one on top of the other. The one on top is flashing (blinking), Do you know what that means? This unit does not comes on in the heat mode. I checked and the board is getting 24v to it, but when, I checked the voltage from it to the coil of the contactor, there was no voltage there. I am thinking that this board IS defective. Could it be that this board flashing is saying something is wrong it? or is it normal? Please. If you (or any other) have an answer, for this, it will be appreciated. Thanks.@@JerseyMikeHVAC

      Thank you again so much, Mike. I am now really understanding it all. I check the defrost board, and there 24v going to it, BUT. No voltage coming out, (to the contactor coil), in heating or cooling mode. So, i think the board is defective. Do agree, or could there be something else that is cause this issue?

      @@korruptsociety421ok. That’s not a heat pump. What kind of thermostat do you have?
      Sounds like you have a heat pump thermostat. What may be happening is that your thermostat is made to activate back up heat after a certain time delay if set point isn’t being met, but it still thinks the heat is on in heat pump mode. That’s why your blower is running but no heat is coming out.
      Switching the white wire over to E and setting the thermostat to emergency heat mode can work to activate the heat strips immediately on a call for heat but it would be better to have a non heat pump thermostat.

    Thank you so much for this video. I have an issue that I am hoping you can assist with helping me solve. My Rheem heat pump system in the HEAT MODE does NOT turn on the outdoor unit. The indoor unit however comes on and blows air. So, I turn off the system, wait a few minutes, and then put the thermostat in the COOL mode. The same thing happens. The OUTDOOR UNIT still, did not come on. This was working fine in the summer. I live in Orlando. But now switch over to heating, and I am, all of a sudden having this problem. Is it the thermostat or the defrost board, that is not functioning? I know it one of the two, but just can't figure out which one. (the compressor comes on when I push in the contactor manually, so i am happy the our door unit seem ok). If you (or any other could help here, I would really appreciate it). Thanks again for the good work that you put out to the public.

    • @JerseyMikeHVAC
      @JerseyMikeHVAC  10 месяцев назад

      It could be the defrost board, but I couldn't say for sure. I wouldn't suspect the thermostat if both modes aren't working, not that it isn't possible, but that would far more likely be a dead battery or charging issues to have such an outcome.

    •  10 месяцев назад

      hey Mike, what is a "high pressure lockout"? And could a defective thermostat caused the defrost board to show this code. My heat pump board is currently showing this code. The OUTDOOR unit DOES NOT, start up at all, in heating or cooling. There is 24v on the R and C terminals. In the "emergency" mode, I am not getting enough heat. It only heats up to 72degrees only, and runs all night. And never shuts off. This is a RHEEM system. 6yrs old. I am really frustrated now, because i am having all these issues at the same time. I am thinking the thermostat is mal functioning, then I think its the defrost board. then i think the heat strips has issues. I am a wreck with these issues. The indoor unit runs fine, but NOTHING from the OUT DOOR UNIT. I just can't figure it out. Hope you or any other can assist me. Thank you, again.@@JerseyMikeHVAC

    • @JerseyMikeHVAC
      @JerseyMikeHVAC  10 месяцев назад

      The hi pressure switch is due to high refrigerant pressure being sensed near the compressor. It locks out the unit to protect the compressor from being damaged under abnormal pressure conditions. It will not automatically reset. It has to be done manually at the pressure switch. This usually requires some disassembly of the unit to reach.
      Usually what causes this is either a dirty or obstructed condenser coil blocking airflow or possibly an issue with the condenser fan motor not running (which could be a capacitor issue or a bad condenser fan motor).
      But it can be other things as well, like a plugged txv, kinked refrigerant line, etc. If the unit is only 6 years old, I would test the capacitor and make sure the condenser coil is relatively clean as a starting point.
      You have to be careful. There's a lot of high voltage there and those capacitors can hold a deadly charge even with the power off. Don't leave your comfort zone.

      I'm not aware of one, but lack of airflow will drastically alter refrigerant pressures and will trip off temperature or pressure sensors.

    Hey Mike, what happens if you connect the R wire to the W wire in a heat pump system? in this case I thought the W wire calls for heat, but when I did it with a pair of alligator clip wire, the wire melted so I disconnected it.
    I read up that in heat pump systems, the W1 wire might be E or AUX on your diagram, so what happens if you connect R to E or AUX without the thermostat attached, so in this case I guess based on the last few minutes of your video, R is connected directly to W(E or AUX), without O and G

    • @JerseyMikeHVAC
      @JerseyMikeHVAC  Год назад

      I've never seen a jumper from R to W melt. Only thing I can think of to cause that is a high resistance caused by improper wire gauge for the voltage, a very loose wire connection or maybe a ground fault.
      What kind of thermostat is it? W1 on a Honeywell can engage the heat strips even during cooling mode, which is why Honeywell says not to use the W1 terminal on heat pump systems.

      @@life.b.s I just realized it's possible that you activated the heat strips without the blower running by jumpering R to W, and I suppose it's possible the resistance went high because of it.
      To activate heating mode on heat pump system with a jumper, you only need to jumper R to Y. The reversing valve defaults (on most systems) into heating mode when not powered (O terminal), so to run heat, you jumper R to Y and that activates the compressor, CU fan motor. and blower; basically the system runs in heating mode by default. Always check if the blower is running though, some systems are set up where you need two jumpers to make it work (R to Y and R to G, etc).
      R to W is for boilers, furnaces, etc.
      R to Y is cooling mode for straight cooling.
      On heat pumps, R, Y and O must be powered for cooling.
      On Rheems, Rudds and a few others, R, Y and B must be powered for heating, while R to Y activates cooling.

    •  11 месяцев назад

      What would cause you to want to connect R to W?
      The R is the HOT side of the 24v, from the supply source (which is the transformer), I understand this base on Mike JM's teachings. Thnx JM.
