If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.
Assuming we are talking about a Heat Pump system with an outdoor condensing unit and an indoor air handler, it is not uncommon for electric bills to escalate during the harder winter months.
Typically, the auxilary heat light energizes whenever the electric strip heaters are in use. These heaters are used to supplement the heat from your heat pump system which will be unable to maintain desired occupied setpoint with outdoor temperatures below 35degF. At outdoor temperatures below 35degF is not uncommon for the heat pump to run non-stop and the electric heaters will cycle on and off as the temp in the house drops between 1/2 to 1 1/2degF below setpoint. The electric heaters will also come on when the system goes into a defrost mode...defrost modes typically last anywhere between 2 - 8 minutes. The emergency lights, depending on your thermostat, will come on whenever the thermostat is placed in EMER HT. Some systems energize the emergency heat lights to indicate there is a problem with your condensor unit.
I suggest you ensure the thermostat is in HEAT mode and not EMER HT mode. Also, while the system is running, step outside and visually inspect your condensing unit. Is it running? Does it appear and sound like it is running normally?
Don't forget your air filter. This is the single most important and most-neglected maintenance item on your system.
If after these steps, you still feel as though you are having problems and would like to try and correct them yourself, please let us know.
I hope you find this information helpful. Good Luck to you! :-)
A basic model heat pump with an air handler with electric strip heat generally will continue to run with a call for heat regardless of the outdoor air temperature unless there was an outdoor thermostat (an accessory) installed. There is still heat in the outdoor even at temperatures of zero and below. Generally, there is a balance point of approx 30-35degF that allows the heat pump to heat your house to 68degF without the need for the electric heaters. Below that, the heat pump can still extract heat from outside and "pump" it into your house; however, it will need help from the electric heaters. In temperatures below the balance point, the heat pump will run non-stop. As the temperature in the house falls approx 1 - 2 degF below the setpoint, the electric heaters will energize. So it is not uncommon for the system to run non-stop with the temperature falling a few degrees below setpoint. The colder the outside temperature, the more often the strip heaters will cycle on/off. If your system is well-maintained and operating at proper performance, it is still cheaper to run your heat pump than it is to run on straight electric heat. If you live in a climate where below zero temperatures are normal during the winter months, you might want to research heat pump options that offer higher COP's and increased performance in colder temperature than the basic contractor's model. Start with initiating communication with a local contractor. You will need to consider initial cost and the pay-back period based on your local energy costs and your specific demands you want your system to meet.
Take it to another shop, The water pump doen't hold the Thermostate. The thermostate is in the thermostate housing where the end of the radiator hose is connected to the egine.
There are different thermostate rating to which temprature you'll like your engine running at. Most common would be a 190 thermostate you can get them from 160 up to 220.
As for the water pump you would know if that failed do to over heating or leaking from the weep holes in it.
Bring the truck to another shop and have them flush and Antifreeze if it's never benn done and change the Thermostate to a 180 or 190 and should be done every Two years do to waer and tear. Note the 180 runs cooler then the 190 and so on.
I run mine on 160 since I tow a trailer and the radiator also cools the transmisson oil too. Just for though but you should be fine at 180 or 190.
Good luck and hope this helps.
Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
Welcome to the wonderful world of electric heat pumps (lol).
your cycling thermostat needs changed too. the thermal fuse is your last safety measure that goes, which means your cycling thermostat is not shutting down the heat element once it detects the right temp hot air in the blower housing so it let the heat element glow until either the high-limit sensor shuts the heat down or the thermal fuse blows. Change the cycling thermostat and good luck
Make sure fan relay is wired correctly (G) wire. Ensure the fan on therm is not on, it should be on Auto or off.
If your furnace is short cycling because it has to keep heating your home, the delay in the control board may be staying on to compensate for the exchangers getting hot. If it heats normally, then put your attention to your thermostat.
Set the heating system on aux heat only. Fan should not be on, if it does stay on after a heating cycle, see if the furnace is heating normally, and reaching temp as desired before the heat comes off. Then check the therm wiring, pull the face of the therm, disconnect green wire (fan) and try the heating again.
If your unit is blowing heat inside and it's not a heat pump. It will be most likely electric heat in your case.
Sounds like you have a split unit meaning the condenser is outside and the cooling and the heat features are inside or under your home.If your Rudd is a heat-pump the outside unit will cycle/blow cold air outside in winter and hot air will cycle/blow outside during the summer season. Now, if for some reason the heat is not coming on inside the house, would be the only reason that you would need to be concerned. Being a heat relay or breaker of could cause that problem. Hope this helps you, Sea Breeze
