Reset button keeps popping out causing dryer to cool down and no heat until pushed back in?

To start with, the tech charged you for an hours worth of service and only pushed the button. GET YOUR HOURS WORTH!
•The outdoor coil needs to be cleaned. Turn off power at the breaker and t-stat, clean the coil with water hose
•The outdoor fan motor may be slowing down or stopping due to motor bearings dry or weak run capacitor. Any noise/squealing from motor?
•Too much freon in the system.
•A restriction in the freon system.
•A improperly installed/mismatched system
•A (kynk) in the liquid line(3/8 copper)
•A stopped up or clogged filter dryer
•A dirty indoor coil that has an expansion valve(txv) will run too cold and the valve can close near "seated"
All of these, and more, can cause a HIGH PRESSURE SWITCH to open. When yours open, you have the red button to push which resets it(the switch). I have also found that the plenum(duct box that connects to your indoor unit at the discharge air) is supposed to be tapered to the air opening size of the blower outlet but that's hard to explain. If the plenum size is the same size of your indoor unit, width and depth in the upright position, the your plenum is not "tappered"(goes from one larger size to smaller size where connected to the I.d. unit). In that scenario, the high pressure switch opens during heat operation, not cool. I know, confusing. Try cleaning your o.d. coil first. And try to get an hour of work(or close) for an hour paid. And WORK SAFE!

If the sensor knocks the unit off and the the fan keeps blowing without a flame ,the limit (the sensor is a limit comptroller that turns off flame @ a set temp and allows the fan to run until the heat exchanger cools to @ set temp) has out lived its lifetime and needs to be replaced.the button is a manual reset that once reset would allow the unit to continue to run flame and blower at the same time after having been set once, if it is an ongoing problem and needs to be reset more than once then replace the limit control (sensor) in kind. (With the same mode and set-points for the limits)

Mike, These dryers temperatures are controlled by a thermostat if the thermostat fails there will be no heat generated. Some thermostats are re-setable. If the dryer temperature becomes excessive it trips by popping out a button on the top, which can be re-set by pushing down the button on the top, until it clicks back into place. TURN OFF ALL POWER and UNPLUG THE APPLIANCE BEFORE ATTEMPTING THIS OPPERATION.

You are tripping that outlet's breaker. Either too much is on that breaker and circuit or that circuit is not big enough, enough current to power that unit.

If the switch keeps popping, that means there is a problem that the switch is keeping from causing anything from a complete failure to a house fire. As you have asked about a "quick fix", must assume you do not have the required expertise to diagnose the different components. You should call for an appliance maintenance person to come out and fix it instead.

Hello, Welcome to FixYa.

There is indeed a reset or hi-limit as it is sometimes referred to on the element/heater box at the back and it should have a red button in the center you can physically push with Bosch...at least the "nexxt" series.

To start...

**Unplug the dryer before attempting any repair tips suggested here please...safety first**

If you`ve already taken the back of the dryer off to gain access you should have no problem. If you never have, it`ll take some time.

For resetting the hi-limit cut out, you can see through the back vent opening when the vent is removed and then by pushing the red button in...shown below

i.e.


Keep me posted how you make out or if anything is not clear.

The motor is bad and needs to be replaced.

Well it sounds like a sound I have heard... forgetting that I had a cigarette lighter in my pocket and having it explode from the heat in the dryer. But you say you heard two loud pops?

Once everything cools down, check again and report back... does the dryer not turn on at all? Does the light come on when you open the door? Does it buzz when you push the start button? Stuff like that.

i found a reset button under my fp dryer. Lift up the front (with some help to hold up) and with a flashlight you should see a red reset switch that resets the heater elemnt. this is a safety precaution built in. when i was having this plroblem it was being caused by the vent leaving the dryer clogged and bent to sharply, i solved this by playing with it until it seemed to make a nice smooth bend.

I had the same problem. Turns out the reset button on the back of the dryer needs to be pushed; when you push the reset button you should hear a click. If you do not hear a click the problem was probably not the reset button. The button shuts down the dryer heating elements if they are getting too hot and also keeps the drum from turning unless the start button is held down.

If you push the reset button and the dryer starts to work again, I strongly recommend that you stop the dryer and investigate why the heater elements overheated. In my case there was lint/hair build up on the heater elements themselves. Extensive dryer disassembly is required to properly clean the heating elements but it is worth the prevention of a house fire. While you're at it, clean the rest of the machine and the duct work.

Hope this helps
