When i turn My Solara DSC VHF radio on it no longer beeps . I cannot hear any squelch or pick up any channels. Is this my speaker that has gone.


To test a speaker, you'll need either a digital multimeter or an analog multimeter that can read measurements of resistance (Ohms)
First isolate the speaker from the amplifier (meaning, remove the wires attached to the speaker terminals).
Set the meter to Ohms (Omega symbol).
Take the meter test leads and place each one on the speaker terminal (make sure the test leads do not touch each other)- there is no polarity to this test so it doesn't matter which test lead goes where on the speaker terminals
For an 8-Ohm rated speaker, you should get a reading of about 6-7 Ohms (approximately 15% of the speaker rating)
For a 4-Ohm speaker, around 2-3 Ohms
and for a 16-Ohm speaker, about 8-Ohms
If you can an infinite reading (make sure the test leads are not touching each other) other wise, if the test leads are not touching and you get an infinite reading, there is a short in the voice coil; speaker is defective.
OL reading on the DMM, or O Ohm resistance on analog meter, broken wire connection inside the coil= open voice coil and is defective.
If you get the proper reading on your speaker, the problem IS NOT with the speaker

How do I check a thermal fuse and heater with a digital multimeter on my Samsung rb215lash refrigerator?


Hello Sylvia;

My name is Peter. I am a retired field service technician.


You need to unplug the sensor. Place the bulb in a glass of ice water. After 10 minutes, Set you multi-meter to the lowest Ohms (Omega Symbol), touch the meter leads together you should get a reading of '1.0' or 'OL' the connector has two plugin ports, with one meter probe on the one port and the other probe in the other port, you should get a reading of 16 Ohms.

You have three sensors, one for the freezer, one for the evaporator coil and one for the freezer:

25316535-e0goqiu2jemxlrpk4czrq0zz-3-8.jpg

You have two defrost heaters they are part of the drain assemblies: Once again, set your meter on the lowest Ohms. Put one contact in one connector port and the other lead in the other connector port, If you get a reading of '0' or infinity the heater is bad. If it is good you should get some reading 25 to 150 Ohms.

All of these components are behind the back fresh food section and freezer wall.

I am sorry you bought a Samsung. 65% of all of my service calls were either Samsung or LG.

Control on whirlpool EEZ8OHD055V Blinks twice, no hot water


1) Call Whirlpool. 1-877-817-6750
Have them send 2 new thermistors (temperature sensors located above each element), and then install according to the instructions they give you.

2) Sounds like you have the American brand older energy-smart electric water heater with grey control box on top
Copy following link to exactly identify product and resources

3) Two flashes is 'high water temperature shut down.
Buy cheap multimeter from hardware store. Install battery. Set to read ohm, the upside down horseshoe symbol.
Use multimeter set to read ohms, and test thermistors
Copy following link for general service manual showing error #2 and thermistor resistance chart on page 10

Freezer makes ice but won't dump. water works fine


How to Test the Ice Mold HeaterA modular unit will have several holes in the module, each marked with a letter (similar to the one pictured below). These holes are for test probes. If there are no holes then the ice maker is a component model and the components can be tested individually.Conduct this test with the refrigerator unplugged. Test the control module heater for resistance using a multimeter. Set the multimeter to the ohms setting X1. Place one probe into the hole labeled "H" and the other probe into the hole labeled "L". The multimeter should read in the range of 60 to 90 ohms.
If the heater does not pass this test, replace the ice mold heater.
How To Test the MotorConduct this test with the refrigerator unplugged. Test the control module motor for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place one probe into the hole labeled "M" and the other probe into the hole labeled "L". The multimeter should show continuity, with resistance possibly as high as 10,000 ohms.

I have a Reliance 501 electric water heater. There are two panels. In the top panel is a red "reset" button. On two occasions this button has popped and turned off the unit. I have pushed the...


ECO reset button trips when thermostat senses high heat event over 150 degrees F, or when upper or lower thermostat is defective. There are other causes: if tank access covers and insulation are missing, and when element is shorted to ground in center of element so that element continues heating through one leg of 240V circuit after thermostat turns off.

Ordinary tank-type electric water heater is fully repairable by homeowner using generic parts from hardware store or home center.

1) Replace upper and lower thermostat for about $28, and if problem persists, then do troubleshoot shown in step 2 below.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

2) Take 30 minutes and troubleshoot before replacing any parts.
Troubleshoot requires cheap multimeter from home center.
Install battery in multimeter.
When testing voltage, rotate multimeter dial to 240 or 250 or 277 VAC.
When testing continuity or elements, rotate multimeter dial to ohms (upside down horseshoe symbol is ohms)

I have a Rheem Electric water heater Model#71-52DB. It has no power and not heating when it does have power.


You need to troubleshoot water heater and electric going to water heater.
Troubleshoot takes about 45 minutes.
Typical electric water heater tank is fully repairable by homeowner using generic parts from home center or hardware.
Links below walk you through the steps:

http://waterheatertimer.org/Test-electricity-to-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Buy $5 multimeter from Lowes or Home Depot or Ace:
Install battery in multimeter.
When testing voltage, rotate multimeter dial to 240 or 250 or 277 VAC.
When testing continuity or elements, rotate multimeter dial to ohms (upside down horseshoe symbol is ohms)

Trying to find neg wire on coil pack on a 96 ford cotour 2.5 v6


Get a digital multimeter ($10 at a parts store). Set it on the ohms scale (the omega symbol). Touch one probe to the chassis, and use the other to probe the wires on the coil pack. When you get one that shows very low impedance (a couple of ohms or less), that'll be your negative.

Trying to understand the continuity check for F06 error


When you do a continuity check you do not have it plugged in. It is best to unplug at the motor so there is no feedback.
