Re: Put in a new heating element,no hot air
Now that you replacetheheater you should be able to check the thermal fuse and possibly the high limit thermostat. both mounted right by the heater assy, if open(no continuity) on either of them yo will get no heat. also first check your incoming power. you MUST have installed on rear into the terminal block and-in this order(black and red can be switched but white MUST be in middle. RED(110v), WHITE(nuetral), BLACK(110v). black to white 110v, red to white 110v, and then black to red should measure at least 220,

Replace the thermostat. A very inexpensive thermocouple that is not sensing the heat anymore and caused the element to overheat. In the UK the part will cost less than five pounds!
If the element had touched the ground, your safety earth leakage breaker in the fuse box would have tripped.
make sure the vent system is clean. any restrictions can cause the safety switches to activate and turn off heaters. When it cools, the switch resets and starts heating. Unit will continue to cycle the heat off and on. Make sure all elements are working.
Double check the circuit breaker for the dryer (Electric Neptune). Turn it off, then turn it back on. Its possible that the breaker may have tripped for some reason, but wasn't able to trip all the way.
Does the interior of the dryer get warm at all? You could have a 1 of multiple heating elements that has shorted. If no heat at all, the likely a heating element has opened up. Unplug dryer from wall (turn off circuit breaker first!). Use a ohm meter to measure and check continuity of the heating elements.
There may also be a sail switch in the air path of the dryer. The purpose of the sail switch is to keep the elements turned off until there is enough air blowing through the dryer. This helps prevent fires, as well as shrunken denim.
It might just be that your vents are clogged up. Go outside and place your hand over the vent to see how the air flow it. It should be pouring out air fast. If it is slow or not much at all then that could be your problem. If there is not enough hot air escaping the heating element is going to be shutting off for safety. The thermostat will sense that it is too hot in there and turn it off thus requiring more drying time. This is usually the problem. If this is the problem just have your vents cleared out. This is something you will want to do at least once a year. If you have a long distance between the dryer and the vent exit there are probably bends and such in the hose. The bends will catch lint and it will just build up. If your vents seem to be fine then you may need a new thermostat. The heating element isn't the problem. They either work or they don't. The thermostat controls the heating element though and how long it stays on. It monitors the heat in the drum and when the dryer reaches the desired heat it shuts it off. Check the vents first though. I hope this helps you and good luck. If you have any other questions let me know and let me know if this was helpful to you or not.
First you need to know if the element is heating up. Are the clothes hot? If so, you need to check your vent hose and duct. A clogged vent will not let the moisture out and will cause long dry times.
If the the element is not heating or barely heating, you need to check your wiring. Make sure the power cord is properly installed. If you have 4 wires in the cord, you will have black and red on the ends with white in the middle and green to cabinet.
If you have a fuse box in your house instead of a breaker box, check the fuses. There are 2 fuses for the dryer. The element needs both fuses to work but the motor will still run if one blows.
Post back if you have any questions.
