Hello -york electric furnace- no emergency heat- with heat pump

Hi David. I'm Roger. For some reason your picture is blocking half of your message from sight. Could you please send me all you can in information but no picture. Your message is blocked from " I put in 20L of diesel for emerg, and now it works," -----That's all I can see. Tell me what you can and we will get started on for you.

If you have a heat pump the electric heat is the emergency heat. Short explanation of a heat pump is it switches the jobs of the indoor and outdoor coils. So instead of taking heat from inside and moving it outside it works backwards picking up heat from outside and moving it indoors. Probably an electrical problem.

All York/JCI thermostats made by Venstar

The setup is probably incomplete. Did you configure the thermostat for a 2 stage heat pump? The heat pump should have a thermostat wire connected to R, C, Y1, Y2, and O, that makes 5 wires. I suspect you are only using first stage compression and or first stage blower speed.

Yes, if you are talking about a heat pump. It you have an electric furnace inside, the electric elements are for emergency heat. Otherwise, unless you switch it manually at the thermostat, the heatpump (outdoor unit) will run all year around. If you want to use your inside heater (electric heater) just switch your thermostat to "emergency heat" and it will turn on the electrical elements instead of the outdoor unit. This way will make your elec. bill higher tho. The heat pump is much more efficient. Hope this helps you , have good day

Is this an electric heat unit or a refrigeration cycle heat pump?
If this is a refrigeration unit, it could be a charge/pressure problem.
If this is an electric heater, is the blower working? The blower must be on or the element will overheat.

by going to emergency heat you have shut off your heat pump and turned on a back up source,either gas or electric, if its cold out,35or less ,just leve your emergency heat on till it warms up a bit

Actually yes! You can install electric elements in the plenum that turn on by your thermostat. The convection blower from the furnace can be used. You can also install a heat pump system that will give you both heat and air conditioning.

It actually sounds like you may have answered the question yourself. If the mercury isn't breaking contact, then obviously it's still calling for more heat. This is a common problem with the old mercury thermostats and are usually replaced with digital ones that are way more accurate. The are fairly cheap at Wal-Mart and such, and replacing one is basically all color coded.

Don't know how long you have had a heat pump but thats the nature of them in colder weather. Some people prefer to switch to "emergency heat" on the t-stat when temps fall below 20 or 25 degrees. This bypasses the heat pump and allows your back-up heat to heat the house. If your house is total electric your emergency heat is an electric furnace and it should handle the load if it was sized properly. Don't leave it on emergency when it warms up because your heat pump is much cheaper to operate than the furnace. As always, check your air filter since it can restrict the amount of air that moves thru the furnace, which is critical. Hope this helps

yes i can , you need to hookup the r and the o together so that the reversing vvalvce is allways energized . so with that im mind send r,y,c,o to theout side unit. at the ahu you'll hook up the 5 wires for the furnace, r g w1 w2 com and at the thermostat r,w1,w2,y,g,com,o then you will be set (the o get hooked up to o and goes straight out side.
