There are several devices in your system. You replaced the the thermal cut out designed to interrupt power when the temperature reaches 250 deg F. A thermal fuse is also installed which "blows" at 390 deg F. A third control device is the thermister which signals the control board to control air temperature. When it fails the system is designed to generate signal such as beep-beep-beep. To test the heater itself you can disconnect one end and measure resistance to determine that the heater is not burned out. Also you can read the voltage applied across the heater (if there is voltage but no heat the heater need replacing)
The control board gets a signal from the sequencing system. The manufacturer will provide a schematic for your machine if you ask.

No heat

First check the voltage and make sure you have 220 volts. Next check and see if the heating element has resistance and check the small thermal fuse at the top of the heater housing. If the fuse is trip you need part 279816/. Replace both the thermal fuse and the high temp thermostat on the side of the heater housing. They both come in the part number I gave you. .Then check and make sure the vent hose is clear and straight as possible. and you should be golden.

Dryer not heating mod # 110.64652400

you may have several problems, first, check the thermal cut-off with a meter(continuity) at the side top or the heating element. if not beep or mesure "0" on the display then is bad, change it as a kit#279816 part# at Sears. if is good(it beeps) then check the heating element for ohm about 10 to 12ohms. if it reads "0" then is bad, part#279838. if is good then check continuity on the thermal fuse at the blower housing(a white 2prong part) if it not beep then change ir part#3392519. all parts at Sears Website or Sears Service Center. good luck to you.

Model RES7745PQ0 works great but no heat... what is most likely the problem... also I checked my breaker so that's not it...? HELP\r\nBest Regards

The problem is likely in the thermal cut-off (cut-out) and the high-limit thermostat located on the heating element housing. Verify this condition by bypassing the said components. Disconnect power then remove the rear access panel to access the thermal cut-off (cut-out) and the high-limit thermostat. Disconnect the wires of each component then connect them together and insulate it properly. Reconnect power then start the dryer. The problem is indeed in the thermal cut-off (cut-out) and the high-limit thermostat if the dryer heats up. Replace both parts and it should solve the problem. It is an easy and cheap repair to make.


thermal cut-off (cut-out) and high-limit thermostat are sold as a kit with part number 279816 and costs about $30.

In case the dryer still doesn't heat up with the
thermal cut-off (cut-out) and high-limit thermostat bypassed, bypass the cycling thermostat then replace it if the dryer heats up. Check the heating element for broken coils if the dryer still doesn't heat up with the three components mentioned above bypassed.

My dryer is a supreme 7cycle 4temp, model LER7646EZ0. No heat. Is resistance of heater coil around 9omhs? Voltage on one end of heater coil is 52 vac terminal to ground.

Set your meter to "beep" when leads are touched together . Disconnect 1 wire from element , then touch both element terminals . A beep , it's good . Touch the small "thermostat" (thermal cut-off ) terminals at the top of the heater box and see if it beeps . No beep , bad . Pt # 279816 . This pt# includes the thermal cut-off AND the hi-limit thermostat . Both must be replaced .
