When I turn it on to the heat cycle the fan does not run, I have swapped the control board with another unit that was working and still get the same result the unit runs on all other cycles.


This is not true if your system is a heat pump. When the thermostat calls for heat, and the burner ignites the gas, a thermal sensor switch senses when the hot box has heated and then the sensor turns the fan on, this is so no cold air is blown into the ducts and living space. Also, another sensor senses the heat box if it gets too hot, cuts out the burner, if this sensor is not working then the burner will never light. Two sensors that may be keeping the heat from working among other possible causes, one step at a time in trouble shooting. Does the burner turn on at all?

My Bosch SHU9925UC dishwasher will not stop cycling and come to an end. I also noticed that a couple of weeks ago it stopped beeping to signal the end of the wash. Can anyone help me please? Thanks for...


From the Appliance Repair Clinic:

The cycle doesn't complete
If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle
Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

* On some units, the pause is timed and the unit continues after the allotted time.


* On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.

Dishwasher Danby ddw1806bsl wash cycle does not work.


Hello there Adam and welcome to fixya
Most of the time this usually turns out to be a timer problem but i will post you some information on things that will need to be checked also ok?

I have an armstrong heat pump and am curious about how the defrost cycle works.


Rather lengthy but here it is.
The outside unit(heat pump) has a reversing valve, a defrost board, a crankcase heater, a metering device(txv or piston) and an accumulator. This is what makes it a heat pump instead of a straight air condensing unit.
When in the heat mode the outside unit becomes the evaporator and the inside unit becomes the condensing unit.Before somebody corrects me i am just stating what is different in a heat pump.
When the system goes into defrost several things happen. First the system has to call for a defrost cycle. This happens on a time and temperature sequence. When the defrost board times out for a defrost check(the defrost board has a jumper pin to determine how long before the system will check for a temperature(thermal switch) is open or closed. This switch is in the normally open position. It will close at 35 degrees(depends on the switch). This switch is located on the copper line in the condensing unit. If this switch is closed then the system will go into defrost. Now for the good part. This will shut down the outside fan, switch the reversing valve, and the outside unit will essentially go into cool mode. Because the fan is off the compressor will heat up very rapidly and the refrigerant passing thru the coils will be hot as well. This will cause the ice buildup on the outside unit to melt(defrost). This will continue until a temperature is met or it times out. Then the system will return to the heat cycle. One other thing, depending on how your system is wired the inside unit will turn on the auxillary heat while the defrost cycle is in process. That way you will still have heat while the defrost cycle is in process.
It is not uncommon for steam to come out of your outside unit while this is going on. It can also be quiet noisey sometimes.
Hope this explains what you wanted to know. If not just reply to this with any other question you have about the cycle.

Hi


Thanks for using FixYa. If the cycle doesn't complete, then the first thing that should be checked is the Timer and then the heating element. Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it. Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next depends, as follows: On some units, the pause is timed and the unit continues after the allotted time. On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too. Please do accept the solution if the issue is resolved or post a comment for further assistance.

I'm not getting heat from my unit..


the compressor is controled seperately from the fan, this is done with the thermostat, try turning the thermostat on then of or untill you hear the "click" sound from the thermostat. If the compressor is still not turning on this may be more than you can fix if your not familiar with electrical hvac troubleshoting... more than lilkely the thermostat may be bad, or your compressors starting components are failing...if the compressor is comming on when the unit is turned on you could have a freon leak causing no heat. hope this may help some there is just too much to write on the causes this will give you a start though!!

Unit does not cycle


you should check the heating element. if the water is not hot enough, the timer will not advance. crack open the door mid-cycle. let the water stop flying around. then open it all the way up. if you don't get a big ball of steam, you have an indication that your heating element may not be working properly. this is not too hard to check the resistance with a multimeter and then replace, if necessary. good luck

Running time of dishwasher


he cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing
Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water. 

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit. 

Cycle not completing See "The cycle doesn't complete" section.
