Unplug the dryer and the first thing to do is check for the presence of 220 volts at the wall outlet. If you lost one leg of the 220 volts, it is possible for your dryer to run but there will not be any heat. Once you verified there is definitely 220 volts at the wall outlet, remove the rear cover. On the lower right hand side you will see a silver canister which contains the heating element. Remove the lower two wires directly from the heating element and check this for continuity. If it is good, on the left hand side of the same canister they often install a thermal safety which may have tripped. Do the same test as with the heating element. Remove the wires and test the thermal safety for continuity. If this is good, move to the blower housing on the left side of the exhaust vent and look for a white piece of plastic which has two wires on it. Remove these two wires and check this item for continuity.

Wont heat

do you hear 3 clicks when you start it up,these clicks are the gas valves opening to supply the unit with gas for operation,if no clicks are heard it can be the thermal fuse is open,if only 1 or 2 clicks check continuity of the main and secondary gas valve coils as they can open up or get weak from heat during operation,usually just replace both coils on the gas valve as they are inexpensive one has 3 connections and the other has only 2 connections,but first bypass the thermal fuse with a jumper wire (for testing only) then replace the gas valve coils next,unplug both coil connections then remove 2 screws holding the valves to the valve and replace and reverse dis-assembly procedure

TUMBLE DRYER NOT HEATING UP

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:

Oven does not heat

i have had a similar problem before and was fixed by replacing a fuse check to see if you have 2 fuses if not then the next step is to measure the resistance across coil it wont be 0ohms cos if it is your back to a blown fuse instead you should have a resistance across it i suspect you will see a open circuit meaning u need to buy a new coil for your top oven
hope this helps
