In this type of system (heat pump), the evap and condenser swap functions by means of a reversing valve, according to the mode selected. Evaps throw off cool air, condensers, warm air. In heat mode, the condenser is the indoor coil and it throws off heat from the outside air. Vice versa for the cooling mode. Heat Standby would be whenever the temperature thermistor has reached set point by the user and shuts down the system. Heat defrost is the cycle that reverses refrigerant flow and defrosts the outdoor coil by sending warm refrigerant liquid to that coil. In heat mode, the outdoor coil builds frost and ice on its surface.
Electric dryers have a heating coil over which air is drawn to heat it up. Unplug your dryer and use a continuity tester to check the heating coil for breaks. Attach one lead to one coil terminal and the other lead to the opposing terminal. No reading indicates a burned out coil (very common). All coils are replaceable.
When the ignition module was tested,they most likely did not run it and then test it,when the ignition module does this,it will check good,until it is heated up,with the run mode setting on the tester,so have them do this when they test it,but,it is most likely the problem,if not,the crankshaft sensor is the next likely problem.If this was helpful,please rate,thank you.
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Sounds like your problem may be with the heating coil.
Remove the back of the machine and try to locate the air duct going from the blower to the drum. Normally inside the air duct you will find the heating coil and the thermostats/thermistor.
Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST. This could cause a fire, as you have removed the safety of overheat from the machine.
I will include these two websites for parts and further help:
Faulty gas valve coils are the typical cause of this type of "cycling". These electrical coils are right above the gas valves and when energized, these solenoids open the gas valves and permit the burner to light. If any gas valve coils are suspected of being faulty, it is recommended that both (all) be replaced at the same time. Hope this helped and best wishes.
Maybe you already know this, but occasionally the coils will swell when you first turn them on and they expand to the point of arc'ing off the housing. This puts you right back to square one. I learned the hard way to buy the entire assembly when changing and not just the coil. Not sure if this is your problem or not, but worth another check. I believe the next step would have to be in the control system.
Dehumidifiers and how they work Heat pump dehumidifiers
Dehumidifiers use a heat pump (similar to an air conditioner's heat pump) or chemical adsorbents to remove moisture from the air without cooling the air.
A heat pump dehumidifier uses a fan to draw indoor air over a heat exchange coil. The coil is almost freezing. The water in the air condenses on the coil and is drained. A second heat exchange coil reheats the air, which the dehumidifier exhausts into the room.
A heat pump dehumidifier dumps heat lost from the compressor and fan motors into the air. It returns to the indoor air the heat generated by the dehumidifier turning water vapour to liquid. I got this off the internet
