How to replace thermal overload switch pacvac 700

It depends on what brand and model you have

Most likely the compressor is not running. This unit has been in service for some time as most of the replacement parts have been discontinued. There are some common parts that are generic that can be found like the capacitor and PTC relay & overload but this would require someone troubleshooting the problem of the compressor not running and determining which part has failed. Then to get COMMON parts it would be a matter walking into an apliance parts supply with part in hand to find them. If the controller has failed.. it is not available. If the fan motor has failed it is not available. The usual failures are as stated above, capacitor, PTC relay & thermal overload. Some one will have to remove the cover of the compressor terminals measure input power, inspect the PTC relay, thermal overload, wiring, terminals on the compressor, then measure the compressor windings for resistance and grounds to the case of the compressor.

If one of the common parts that are generic has failed you can repair this unit. If the controller, compressor or fan has failed your looking at replacing the unit.

Wait 30 minutes and try again, there is a thermal overload switch that resets itself.
Clean all three filters and see what happens.

If you can't smell burning then it's probably a broken power switch or the vacuum got too hot and the thermal overload protection has tripped. Try leaving it off for 15-30 minutes and try it again. The thermal overload will reset itself during this time and it should work again.

In the meantime, make sure you have power to the vacuum, check for any blockages and check that the rollers in the cleaning head will turn by hand. Also, give your filters a clean. Any of these could cause the vacuum to overheat.

If you've already done this and/or power doesn't return after 15-30 minutes, I would start by checking the switch.

A couple of questions . . .

1. Does the power switch feel "normal" - basically does it have a positive feel when you switch on and off?
2. How long had you been using the vacuum before it stopped working?

There is a thermal overload switch in the motor. It should reset itself. Let it cool down for a while. And it should start again.

it does have an internal thermal overload device you need to put the vacuum into the shop they should be able to fix it in a few days

check all filters, if they can be washed do so, if not clean or replace. next check for a clog in the machine and in the hoses. the machine as a thermal device that if it senses an overload or getting to hot, the machine will shut itself off for safety resons.

The thermal switch should reset itself after it has cooled. If it still won't restart after a while longer, put a a new bag in the machine and turn the machine off and back on. The only other things that should keep it from running other than the thermal overload, is the bag being full or the bag not being present. Either of these faults would need to be corrected and then the machine switched off and back on to clear them. I hope this helps. Good Luck!!

Here is the owners manual which goes over some troubleshooting problems.

At first I would think it was the thermal overload, which is covered in the manual. But I would guess that you have let it sit for 30 minutes to cool down and tried again and the vacuum still didn't work.
I would think you may have one of four problems.
1. Your thermal overload was tripped and is stuck and will need replaced.
2. You have a clog in your vacuum lines or the brush roller is froze, which keeps causing the thermal overload to trip.
3. Your power cord has a short, which would need replaced.
4. Your power switch is bad, which would need replaced.
Out of these 4 possible problems I would say the only one you could fix on your own would be problem #2. Make sure the vacuum is unplugged and take the brush roller off and clean it, make sure it moves free. Check your vacuum lines to make sure you do not have a clog, other wise the motor does not get air flow to cool it down causing the thermal overload to trip. As for problem 1, 3, and 4 I would suggest taking it to a repair shop.
Hope this helps, post back.

I know that Karchers steam cleaners have had issues with the thermal overload. I have repaired Karcher machines that got turned on with no to little water in the tank and it would heat up really fast and trip the thermal overload. The thermal overload is to reset it self when it cools down but the problem has been the thermal overloads get stuck and dont reset. When they stick, they will give the same signs you have said. In those cases the thermal overload has needed replaced. The thermal overload did its job to trip, but it fails when reseting. I understand you don't want to throw more money into it, but that is the only thing you can do. You can get the part and do it your self, but they are tricky machines to get into and you dont want to break something trying to get in. Hope this helped.
