Customer Questions and Answers for Heater-Spiral by Bosch

Paul, If you order heater part number 00436460 it will have all the necessary parts to replace the heater.

Hello Ashley, You will need to order 00436460 for the heating element for the model provided.

Hello Chris, the heater should be giving you a reading of 12 ohm plus or minus 10%. You could also test the heater for continuity, hope this helps!

Hello Dragos. When you use a high heat setting like very dry or extra dry and do not turn on low heat, the unit will automatically use both elements. There is no way to manually turn it on. Thank you.

Marianne, You will want to test the thermostats and thermal fuses on the unit. If there is continuity on them then they are good. If not then replace necessary part. IF these checks ok then There are 2 components other than the thermostats which would cause the heating element not to work. First is the motor and second the Control board. The best option is to disconnect the power to the unit and access the heating element. Disconnect one wire that is going to the heating element, preferably the one on the thermostat side. Plug the unit back up and using a multimeter you will want to turn the dryer on and test for 120 vac at the terminal on the heater where the wire was disconnected. What this will do is eliminate the heater element itself and the motor. If there is 120 vac at this point then you know the heater is good and the motor is good because the other 120 vac coming through the thermostats is the control board side of the circuit. If there is not 120 vac at that point then you will want to test the other terminal on the heater and check for 120 vac. If there is not 120 vac then the motor would be bad .

Hello Lisa, A thermal limiter will only open due to excessive temperatures. When there is a "brown out" you should apply Ohms' Law. When the voltage is cut in half, the current is proportionally increased, (doubled). The issue is more likely a control issue since the programming can easily be corrupted by excessive current.

Hello Brian. It is a little low, but if it is closed for continuity, it should be good. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater and thermostats and see if they are good. You can test these with a multi-meter MA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello Bobby, If the unit is cleaned out, the exhaust is clear all the way to the outside, and no wiring has had damage to the insulation, there is no reason why the unit should be unsafe. The heating element, if it still heats, should not require replacement.

Hello Tony, A "thermal fuse" can only be opened by high temperature. This is caused by a restriction in the exhaust duct98% of the time and bad drum seals or other seals in the unit that allows the heated air to recirculate into the unit instead of getting the room temperature air that the unit was designed to get for cooling the units' electrical and mechanical parts.

Randy, Here's some help "To remove electric heater:•Turn off or disconnect electric power.•After removing rear panel screws & one rear duct screw, remove rear panel.•Remove four rear cover screws & two duct screws, then lift rear cover with duct up and away from heater assembly. Disconnect wires.•Slide heater toward rear of dryer until tabs slide out of slots in dryer base." You'll have access to test the heater, hi limit and thermal fuse for circuits and damage. Thanks
