SOURCE: thermostat does not stop heat pump unit

Most of these problems are the program settings on these way overcomplicated thermostats. You will need to re-read the instructions on setting the programs. Or bite the bullet and buy a cheaper and simpler one. If you installed it yourself, make sure the settings on the inside are correct, like gas/electric heat, and 24 volts, stuff like that.

SOURCE: Electric furnace blows cold air before and after warm air.

It is normal. Your house has to go down a couple more degrees because the heat pump is not working. You can solve this by rewirng you thermostat. Take off the wire that goes to Y and tape off. Then take the wires that are marked w and e or w1 and put the wires to yellow. Do not run ac with it wired like this. If you need more information please post me back

The heater relay is located on the control board, a faulty relay or a faulty control board would cause the problem you have described. The fix is to replace the control board. Parts for your unit should be available from most appliance parts retailers, if there is not one local to you, the part is available at www.apliancepartspro.com. along with an exploded view of your unit

Hope this helps.

Goodman gph1348m41ac unit is blowing cool air in heat mode with mid 30s ambient outdoor temp. I turn it off then on and will usually blow warm air but this cycle is becoming more repetitive. any expert...


A heat pump on the optimal heating day (about 50 degrees ambient) will only deliver approximately 85 degree air as compared to 125 degree air from a fossil fueled furnace. The colder the outdoor air is the less heat there is available to be transferred to the living space. At 30 degrees, the heat transfer capability is getting close to negligible meaning the run cycles will be approaching continuous and eventually as the heat pump along cannot maintain setpoint, the outdoor stat or stats will bring on auxilliary heat in the air handler.

If your ambient temp is below the 'balance point' of the heat pump, the house temp will drop a little lower and most times energize the heat strips through the outdoor t-stat. Your outdoor stat could be set too low for the heat pump to carry the structure all the way down to the balance point so when you turn it off and back on, the lower indoor temp automatically brings on the heat pump plus a heat strip or two, thus the warmer air. Second stage on the stat satisfies due to the heat strip, drops them out of the circuit and the heat pump is left running on first stage heat delivering the perceived cold air.

Your outdoor stat could also be not functioning correctly and not allowing the heaters to come on until the system is turned back on reestablishing the two stage call for heat.

Tons of possibilities and not enough room to list....

How do I make my honeywell thermostat turn off right away at desired temperature. it runs for about a minute after letting cold air in.


Hi, what causes the stat to continue to run is the heat anticipator setting in the stat. If you have gas heating, it could also be the setting on the fan limit switch. If it is shutting off, and takes about a minute this is pretty much the norm. Once its satisfied, the heat exchanger has to cool down and there is a time delay when this happens. Yes, the air will be cool, but just for a minute. You may have to set your stat a little higher to compensate for this delay. Yes, the fan will run after burner shuts down and it will then cycle down. If it runs and never shuts off, then I would say you have a real problem with the fan limit or relay. Try what I asked. There is not much you can do. The anticipator is a setting in the stat that is set at the factory. Its about 0.4. If you have your stat manual, it will tell you how to check it. Good luck,

Furnace shuts down before heat temp meets thermostat. Furnace unit starts frequently. Service installed new limit switch and a new circuit board but furnace unit continues to malfunction. Same problems...


has any one checked your thermostat. as soon as the furnace shuts down then turn up the stat and see if it starts right up. i would think the stat function should have been checked also.

Hi, sounds like you have a problem with the heat anticipator in the thermostat. If you replaced the fan limit, and with it running that long after the burners shut down, it would be in your stat. If it fires up after resetting breaker, was the stat set to call for heat? If not, the stat is faulty. If you remove the front to get to the stat wires, take a jumper wire and jump from RH or RC to W. Heat will start. Let it run for a minute or so and remove wire. If the fan shuts down with in a min. or so, you will know it was the stat. Good Luck and let me know the out come!

I have a Lennox model CB19-51-1P air handling unit with HP19-511-1P compressor heat pump unit. I just turned the heat on for the first time this season. And I am getting low heat volume. The heat pump...


first thing you need to check is if the reversing valve is working you maybe running your A/C with the heat strips on depends on the t-stat your using some heat pumps will bring the strips on with a high degree difference in setting and room temp .

1- turn t-stat to heat set temp 10 degrees above room temp if you have a programable t-stat it will have a time delay on it allow to for the outdoor unit to come on 2 to 5 minute usually .
2- walk around to the outdoor unit when it comes on feel the big line the insulated one and see if it is hot or cold let it run for a 5 minutes peel back the insulation and gently grab the line with your hand it maybe real hot so be careful if this line is hot then your heat pumps is working mechanically and if it is just warm then you may need the charge topped off

there are so many different option's from this point i will need to know the findings of this test first thanks : Michael

Hi the cylinderstat controls the hot water only not the heating the boiler stat controls the water temp the room theromstat controls the rads , if you have one ,

so boiler stat set on 180f or number 5 cylindersat set on 140f to 120f roomstat to your comfort , the boiler stat works as a over heat so if the cylinder stat or roomsat fail it will turn off on the boiler you should beable to check wiring from that .

Heat will not turn off.Removed thermostat wile


Hello
Could be a stuck control relay,Tsat completes a circut for this relay to engage,once relay contacts are closed heater will start.and stay on until you reach temp.

once temp is reached relay will open and heat will shut down.

By disconnecting all power to heater your forceing relay to open.or simulating a satisfied temp.

I would have a service tech look at your control relay and t stat.

Janitrol Heat Pump


Jenny,

Sounds to be a system freon leak. The unit and the stat talk to each other and if the temp is not reached and the unit shut down in a set amount of time it turns on the E-heat. Now there are other facts that could be involved, plugged filters, dirty coils inside and out, etc. Check your filters first to eliminate that problem.
