Keep burning power conversion plug on PC board I am running unit at 230 volts I have change transformer also

If you really have 252 volts, you need to contact your electricity utility company. If you are in the UK (fuse in plug clue), you should have 225 to 230.

230 volts Although the normal voltage in the UK is 230 volts, it is not constant. The voltage at your property will vary due to the use of power and normal operation of the power supply network. Our network is designed to ensure that the voltage stays within the permitted tolerance or statutory limits.

It will run fine without the filter if you choose to bypass it. If your 110 volt filter is not up to handling the 230 volts the filter will only go bang and smoke it won't harm anything else. I have looked at the capacitors on a 230 volt filter and they are 250v - 275v so just read what's on your 110v filter. What you need to change is the armature, the fields and the small phase board under the back cover..

If you visited Europe and returned to Canada/America and you used a 120 volt appliance on a 230 volt plug using an adapter things can still go wrong. If it no longer works... open it to view where the cord comes in. The first board or section of the board will be a power section. Often there is either 4 diodes or a rectifier with 4 pins these are the likely culprits. If it has a transformer instead then it likely overheated and burned its thermal cutout buried under its layers of tape. I could make it work again if i was there in person.

Yes the higher the voltage the cheaper to run but you will still need the transformer for the controls and fans. hope this helps.

Bosch is not very good about putting manuals or other documentation online for older products, so I'll have to give you generic advice.

Some electric motors have optional voltage connections. If your motor has this feature, there will be a box or removable plate on the motor with 110 Volt and 220 Volt connections inside. You would need to replace the line cord with a 220 Volt cord having the correct plug for the location you plan to use the mixer, and connect the motor "hot" wire to the 220 V connection in the motor junction box instead of the 110 V connection (the neutral wire goes to the same neutral).

If there is no such option available on the motor, you would also have to replace the motor with a 220 Volt version. Check the labeling on the speed control (inside the mixer) to be sure it is rated for 240 VAC, and check the power label by the power cord. If the label gives a single range of input voltages spanning both 110 VAC and 220 VAC (e.g., "Input 97 V- 265 V") then you only need to change the plug. Unless the electrical parts are all rated for 240 VAC or higher, conversion is not safe.

Some products (especially desktop computers) have a recessed switch on the back that lets you select either 115 VAC or 230 VAC input power. If you have this on the mixer, all you have to do is use a small tool to push it to the other position.

An alternative is to get a 230 VAC - 115 VAC transformer or inverter rated for at least 800 Volt-Amps and wire it with a 230 Volt plug on the primary side and a 115 Volt socket on the secondary side; then you can just plug in your unmodified mixer to this. If you cannot find a box like this, you can buy a "control transformer" from an industrial equipment supplier and put it in a suitable metal box. I recommend including a power switch and a 4 Amp dual-element fuse or breaker on the primary side circuit; you don't want somebody burning up the transformer with a 1200 Watt microwave oven or griddle.

may have burned the motor out.... if this unit has a control board on it most likely would have shorted it out first if a standard/basic gas dryer will a timer knob then power would have either burned timer,or motor up first.... good luck to you that really stinks....

Try the fan switch inthe ON setting rather than the AUTO setting, if it runs, power, both low(24) and high(115 or 230) are present. if not, check breakers and fused outlet if a split system furnace, read for 24 volts at red and common on low voltage terminal board where thermostat wires go on the furnace, if no 24 volts there and poers entering furnace, transformers bad.

You need a serviceman. No really, you do! You are in over your head and you are replacing parts just because you can see them and they are not the likely culprit. I am betting it is the contacters in your condensing unit.

no!   It will be ruined if you try that.
