Grundfos jetpaq pumps?

Good day JQ4. Burned one resistor, par is not visible. Please help with the circuit board or the definition of the resistor on the photo (ready to send). Thanks in advance, Bronis, dbss@mail.ru.

SOURCE: Fan motor on 2000 Caravan works only on high.

For the problem of the blower motor only working on high, I just replaced my blower motor resistor. It is located under the hood on the firewall on the passenger side. There is a rectangular plug that connects to it. Remove the plug (tight space). The resistor can be pryed out. It is just held in with retaining clips. Insert the new part (about $15) and reconnect the plug.

Took about 20 minutes. Blower now works on all speeds as normal.

Good Luck!

SOURCE: driver for vista x64

Today I installed VueScan on my Win7 (7264) X64. After that the 1250 was still not recognized. Go to start and execute/run devmgmt.msc. You will get the hardware list with a yellow marker on your scanner driver. Double klick on that icon. Now you need to go to the second tab (driver program if I translate it) and second button (renew if I translate it) where you can install drivers for the device. Tell windows to search on your computer and point to the VueScan directory (directly on C: , not in programs). Now Windows 7 (7264) X64 will find the driver and your Epson 1250 is recognized. :-) Tested and working.

This same method worked for installing the AlexP drivers for my PS3 Eyetoy on windows 7 (7264). Tested and working also.

SOURCE: My hot water heater sprung a leak and after

pumps of this type will fail quickly without water. They are lubricated, and cooled by the fluid that runs through them.

Faulty Countax PCB with burned out resistor and no Circuit Diagram


You are right to be cautious as it is unlikely the resistor committed hara kiri. The circuit of the board would be fairly simple to puzzle out and draw but I feel the board represents only a small part of the whole circuit of the machine and the reason for the burned resistor could be far from the board.

Circuit boards can be refurbished or more likely an exchange is offered with a refurbished board, but in this case with such a simple board it is likely they will provide only new ones.

The value of the resistor could be calculated by any competent electronics engineer - if he has the will to do so.

I feel you need the circuit diagram of the whole machine or the services of a good white appliance engineer. I suggest you visit the manufacturer's website support section to enquire further.

Grundfos jetpaq pumps


Sounds like a broken connection or a link in the over temp circuit.
Or the controll is knackered.
I would say it is unlikley the motor has failed, I have stripped water related dead seized grundfoss units and freed them back up and they have outlasted an economy replacement unit.
I am assuming your unit is single phase, if it is there should be an internal OL reset.
I am not sure where exactly on your unit but if you open the control box it should be evident.
If it has tripped I would check the capacitor as over time they diminish in capacity which would lead to overloading or not start at all which would trip the OL very quickly.

I have a 1995 325is bmw. i was driving home and the needle went to red. the heat also stopped working the day prior. i also smelt a little antifreeze as well. can anyone help please.


If you dont have heat you definitely need to check your coolant level first. Better make sure to use the right coolant alot of BMWs take G-5 coolant. Then see if you can see water running out of the engine compartment onto the ground after you fill it. The water pump could be leaking. Check the radiator for leaks and make sure your hoses are not leaking if the floor inside has coolant seeping into the carpet your heater core could be leaking. If the water is not leaking you could have a bad fan clutch or a bad resistor on the fan motor or a burned out electric cooling fan. Or something wrong with the circuit for the coolant fan.

I need help on changing a fuse in PMP3000. The mixer went out on us one day, so I hooked it into an amp that we had. It works good as an unpowered mixer, but cannot get it to work as a powered mixer. I...


No, that is NOT what the problem is.

The fuse protects the power supply. The power amps have failed. The usual cause is an arc between layers of the multi-layer circuit board. The labor to repair the power amp module is extensive. I have repaired several.

You can find new amp modules and I would purchase a new one and drop into your unit. The amp module is an HCA2400.

There is probably $15 of parts blown in each side of the power amp and it takes about 6 hours to repair. One has to grind out the burned area (internal layers not necessarily visible on surface) and re-insulate and then install jumper wires to replace those taken out.

Each side of the amp will likely take out 3 switching MOSFET transistors and often a Zener diode. Sometimes a low resistance metering resistor will be fried with smoky residue underneath the board. When this happens two small surface mounted resistors will be blown open. Great care has to be taken when insulating the board damage and replacement of the blown circuit traces.

You can find HCA2400 power amp module replacements for about $175 online.

Use of the unit as an unpowered mixer is a bit dangerous as if arc re-establishes it can fry the power supply taking out two very expensive IGBT's and many other components. If the mixer still works, then your whole power supply is still OK.

Grundfos mq3-45 b has stopped working has and has alarm light on. looking for solution please


There are several reasons for the pump to go into alarm mode: 1. Overheating 2. Lack of water 3. leak on the suction side causing cavitation 4. Bad circuit board
This pump will try to re-start for 24 hours and will go into Standby mode if there is no water.
What happens if you push Start?

PUMP JUST MAKES HUMMINIG SOUND SINCE I TRIED TO RESET IT AND IT WONT PRESSURISE WATER


You have a bad capacitor. It's located inside the electrical cover plate on top of the pump. The capacitor is a white cylinder and if it is melted or burned, it is bad. You can do this yourself.

PG won't release schematic diagrams. Are the burned components resistors? If so, what are their circuit board designations (Rxyz)?
