Something is shorted out somewhere in the system.

You will have to trace down each component to find the short if it can't be found with a visual inspection.

Does the board have a low voltage fuse on it?

Foodsaver Professional II locked up. 3 green lights blink on and off. Is the problem fixable?


I completely diassembeled my unit and could find nothing wrong. I reassembled it and had the same problem.

In my opnion the controlled board has failed; time to guy a new Foodsaver.

The small black rubber covered hole on the left side of the vacuum channel is not the reset button, it is the "lid closed" button.

The seal is not the issue as the lights start blinking right after you turn the unit on.

My whirpool dryer won't spin


It can be due to few reasons and so you can check on them.
1. Check the main power line, trace to the main control switch and its output. If not the switch is faulty.
2. Check the working of the motor, check the capacitor to the motor.
3. Check manually if the drive is free and is not jammed or struck up. If so you will need to overhaul the mechanism.
4. Check the door switch is the switch is faulty the motor will not be turned on.

The quilt does not heat up and the timer does not light up, I have checked the fuse and it is fine, it is only a few weeks old, any advice?


Sounds like a break between the mains plug and timer or a bad connection in the timer. Has it ever worked? If not, as it is so new, return it to your supplier.

Hi, I have an NEC hi-def-receiver, model NHD-1000, just recently it has been turning itself off, power is still there, has 4 lines instead of time but it loses the signal. 4 symbols appear when it shuts...


I had the same problem and found it was caused by dry solder joints in the output pins of the power supply board. Solved it by resoldering the joints.

A downlight transformer has failed it is a 20-105w/va & the primary wires black & red come out the same end as the secondary wires -these are a black &red & 2 others to the light. On the...


your new transformer should be fine unless your downlight lamp is 20w,most are 50w 12v so you should check this first.
As for connection your mains supply (primary) connects red to either of the 2 live terminals and black to any of the neutral.The 2 wires from your lamp then go into any pair of the secondary terminals.polarity doesn't matter that is why they are not marked.The transformer can supply 105 w so 2 50w lamps may be connected.

No, the problem is the photoelectric eyes. Check that they are properly aligned.

Thermastat and furnace


you should have 24 volts between yellow and white wires at the stat when the stat is set to heat and set as hot as it will go. burners should light first then 3 to 5 minutes later the fan motor should fire up. if burner doesn't light check the wires going into the top of the gas valve see if you have 24 volts arriving there from the stat. if you do then the gasvalve is probably bad. you can bypass the action of the stat by jumping red to white on 90 percent of the stats made and in a few seconds the gas valve should click open gas flow to main burner where pilot ignites it. another easy check you can do is flip stat fan switch to on. fan should come on at once. if not then you have either no high voltage to unit or no low voltage ( as in a bad transformer). if the fan comes on you know you have high volts and low volts...by cover i assume you mean the decorative cover but there second cover with the mercury bulbs and all is still there. if you have only the bare subbase then new stat time. sounds like an old furnace if it has a standing pilot, it should be checked for cracked heat exchanger by a pro with a n electronic carbon monoxide detector. NOT a diy item due to the real danger of co poisoning.
