New heat pump needs new blower motor-worried?
Comments (13)Hello All, First my apologies for posting this question as a response to an existing thread. I just could not figure out how to start a new thread and no matter what I tried, I was going in circles. Anyhow, I hope this question is relevant to this thread and will appreciate any answers. First the facts: I had a 5 Ton Rheem heat pump installed in our home to replace an 18-year old Lennox heat pump (Model HP22-461-2P) of about 3 or 3.5 Ton capacity which ran its course of life. The Air Handler is installed in the Attic and the external unit is outside. I bought the unit brand new and had it installed by a licensed HVAC contractor. The model of Rheem Air Handler Installed inside the Attic is RHPL-HM6024JC. The model of Rheem Heat Pump (External unit) is RPRL-060JEC. They are purchased as a packaged unit from a Rheem wholesaler through the web and I confirmed through Rheem officials that the units are compatible with each other and the seller is licensed to sell them. These are installed by a local contractor with a Honeywell FocusPRO TH6000 series thermostat which he, the contractor supplied on his own as per the agreement we signed.. The heat pump is advertised as 2-stage. Now, the problem: From the time it is installed on January 26, 2012, the outside fan is not blowing. I asked the contractor about it, and he seemed not sure, but told me not to worry about it and that it will come on when necessary. Then I read a little bit about heat pumps and also recalled that in the case of the earlier heat pump, the outside blower was running much of the time. Toward the end of its life (i.e., just before the installation of the new unit, however, the outside unit had ice formed all over it, and the fan was still struggling to run. A few contractors who came to look at it to give an estimate said that the old unit pretty much ran its life and that it needed to be replaced. One of them said with so much ice outside the heat pump is doing nothing but wasting electricity and disconnected the outside unit from the socket and asked us to put the inside thermostat to emergency heat because that is how we were getting the heat anyhow. This was the condition at the time of the new installation. The new contractor of course, threw out the old outside unit as well as the in-the-attic air handler and and replaced them with the new Rheem units and installed the Honeywell thermostat FocusPRO TH6000. Since the installation, I kept observing the outside unit and found that it was never running. I contacted the contractor after a couple of days and he said we could test it by turning off the circuit breaker for the outside unit off and wait for 5 minutes and then turn it on to see if it would come. When we did that, the outside unit fan did come on, but within a minute or two after picking up speed, it shut itself off. The home is getting heated, but I am concerned that the unit is running as an electric heater rather than as a heat pump because the outside fan is not running at all. This seems extremely unusual. I wrote to the supplier and he says the problem is most likely caused by wrong installation or wrong wiring. When I asked the contractor about it, he adamantly maintains that there is Zero Wrong with his wiring, but he does not have an explanation as to why the outside fan is not blowing. I wrote to the supplier again, and he says that in the most unlikely event that something is wrong with any of their components, they will replace them under warranty if I get a written estimate and a confirmation of the problem. My guess is that the contractor made some error in the wiring, perhaps a simple one, but am not sure what it is. According to the Owner's manual I downloaded, the Rheem heat pump is with serial communicating technology and it consists of Indoor Air handler, Outdoor air conditioning condensing unit/heat pump, and a touchscreen thermostat. The touchscreen thermostat is not supplied along with the heat pump and air handler. I asked the supplier about communicating technology and he responded that they could supply it for about $400 extra. They confirmed that "The heat pump system is definitely equipped with Rheem's Comfort Control System Serial Communicating Technology. Looking at the specs document you can see that the heat pump is equipped with this technology. The air handler you bought RHPLHM6024JC is also Communicating. This system was designed as a matched Communicating system. In order to achieve the benefits of the Communicating system you will need a Rheem 500 series thermostat. The thermostat is not included in in what you purchased. To keep prices low we sell matched split systems and let customers choose their own thermostats." I would like to know: a) How we can diagnose the reasons for the outside fan not running b) Whether the outside fan is supposed to spin when the unit is on Heat and the temperature is cold outside. c) How we can fix it to ensure that the unit is functioning as a heat pump d) Whether it is advisable to consider purchasing the thermostat recommended by Rheem have it installed. Thank you for any info or guidance you can provide....See MoreNeeding to Replace Furnace
Comments (1)If you have the leisure to consider various alternatives (assuming you're not so uncomfortable you need to get a new system without delay), you should explore the possibility of getting a new system that qualifies for the energy efficiency credits put in place by the Obama Administration. I cannot give you details about that. But our next door neighbor put in such a system just about a month ago, and he qualifies for a sizable tax credit Plus you have the benefit of a state of the art system that will use a minimum of fossil fuels. Another suggestion: if you go to the Energy Saving Forum on this website (I forgot exactly what it's called), you can get a lot of info about things like geothermal systems. They are costly to install, and they have to be done by contractors who really understand the technology. If they're done right, your heating/AC costs will drop down to a tiny fraction of the usual, even in really cold places like Montreal. But I do not think you should go that way unless you are prepared to spend more up front and you can identify a really knowledgeable contractor who knows about this stuff. Good luck....See MoreFraser-Johnston furnace blower motor
Comments (13)Park is usually a dead plug where the wire is put to keep it safe from shorting out against anything. You probably need a new motor. The PCB seems to work fine. If the motor does not growl while operating, the motor is probably bad. If it growls, replace the cap first. As to the techs out there- This is the beginning of my new standards for this site. I will help as much as possible to anyone that seems capable. I will try not to insult the poster. A motor replacement is a good test of skills. You need a few tools, and just a little experience with electricity. Like how to switch off the breaker or switch. I am tired of hearing that someone paid $500 for a new $50 motor. Always replace the cap. No excuses, replac3e the cap with a new motor. Do not pass go, until you replace the cap. Otherwise go to jail for your stupidity....See MoreNeed to replace A/C But not sure about Furnace
Comments (4)Your Bryant furnace should operate problem free for another 5-10 years so I would not be quick to throw it away. My general advise is that if you plan to move within 5 years you should keep it. If you plan to stay in the house at least 10 more years then you most likely replacing the current furnace before you move. It then makes more sense to replace it now and get to enjoy it for the next 10+ years. I would think an 80K furnace at 95%+ efficiency would be the proper size. The AC is expensive because you are selecting the 2-stage model with the WiFi thermostat. You could drop down to the single stage. WiFi is not necessary in my opinion. Also do you need a humidifier? This can be added later if you humidity is below 40% in the winter. I highly doubt you need a 5 ton AC. It is good the contractor realizes your duct work is too small. He should be doing a load calculation rather than assuming and guessing. Do you know how much you spend on AC cooling costs? People sometimes pay a lot of extra money to go from a 13 to 16 SEER AC yet they have no idea what the annual savings will be. I recommend calculating the return on investment on the efficiency upgrade part of the HVAC expense. In many cases the pay back period is very long and not worth it....See Moreseosmp
