[Solved] How to Test Furnace Blower Capacitor Using a Multimeter - Brands, Models, Parameters

Hello, I have a problem and it is rape! I need your help.
The problem concerns the furnace blower, there is a capacitor in it, and I suspect it is broken, because the engine can not start, but when it does, it turns on. I am sending photos of the capacitor, tell me how should I check if it is working? maybe the problem is in the controller, but at the beginning I want to make sure checking the capacitor, I have a universal meter available. Thank you for all the help.

Connect it in series with a 230V 15W bulb and an ammeter. Connect the whole to the network and measure the current and voltage. Calculate the capacity and compare with what on the housing. Possibly buy the same for a few zlotys and swap.

The fastest and safest way will be to buy a new one and replace it. The cost is small.

A capacitor with a capacity of 2?F can already be checked with a simple ohmmeter, preferably one with a hint. Connecting an efficient (discharged) capacitor should cause the pointer to pivot about 2 ÷ 3 mm and return to zero. The measurement can be repeated several times always remembering about discharging the condenser before it by closing the terminals.

You can do this measurement and using a "digital" ohmmeter, but such a device must have a memory of the maximum value. There is no noticeable change in the "numbers" flashing when the capacitor is being charged.

Check the capacitor with this capacity can also be using the LED and 4.5V battery. Connecting a capacitor to the battery in a row with a diode will cause it to flash briefly when in good working order. Remember the right direction of connecting the diode.
You should also remember to discharge the capacitor by shorting the terminals before each "measurement", because checking the charged will not give any results.

If the meter has a capacity measurement, what's your problem?

I replaced the capacitor. Burnt
