I turned on my heater for the 1st time and it only blows cold air on the heat setting.Could it be the electric heater assembly?

Is your heater brand new or has been stocked for long time or haven't been used for long? The problems can be defective heater valve, defective blower motor, weaker water pump and an open thermostat. Furnaces that are electronic based like from Air cond. Bell canyon have heating coils that can be clooged or defective blower motor.

Here are your parts
Parts for Kenmore Air Conditioner 58072187300 - AppliancePartsPros.com

If you go to the Sears parts site they have actual part breakdown diagram.
Unfortunately AppliancePartsPros does not have access to these.

Yes it could be the heater assembly.
Below is the heater. You will notice a thermostat mounted at the bottom.
This should be 0 ohms at room temperature.
I could not find any tech specs on the unit so cannot say for sure what the heater resistance should be. I think it will be around 20 to 30 ohms.
Part number: AP4439760
Part number: AP4439760


The unit is made by LG ans I cannot get a wiring diagram so have to do some guessing. I am guessing that the air conditioner rune off of 120 volts while the heater runs off of the full 240 volts so I would check the power to the unit first.
Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
Check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip if it has one.
Do this with the heater off and on.

I had a leaky radiator pipe which may have let air into the system but have since repaired it.I located the tubes going through the bulkhead and though one seems slightly cooler than the other, it is not cold.I tried squeezing the radiator pipes and feel the presence of water in both 'bulkhead' pipes.I dont find an air release valve on the radiator so how do i bleed the air from the system? What and where is the heater matrix and how to unblock it?
