SOURCE: Furnace runs constantly since blower motor was replaced

Sounds like they wired it direct to line voltage , it should run through a sequencer or fan relay to cycle on and off , your seq./relay could be stuck closed to but unlikely being it was just repaired , call the service company back before you do anything they are responsible.

SOURCE: central air unit only blows warm air , when set on cold

First check to see if your outside unit is working and you can here the compressor running. If the fan runs and the compressor does not you have a problem with the capacitor or wires burnt off terminals. If your not sure you know how to work on this please call a service tech ask for free estimate. If the unit compressor and fan runs you may be out of gas that meanns you have a leak. Either way you need a service tech. You can only go so far without the correct tools to work with. Russ

SOURCE: My LG Lan125HV works fine on air conditioning (

I talked to LG customer support (800) 243-0000. The tech told me that this model had a problem with the indoor thermistor. It doesn't fail with an open-circuit condition, so you don't get an error code. The thermister just goes out of range and believes your indoor temp is much hotter than it is. That's why the heating never comes on. I'll bet that, even though it ran in COOLING mode, once your room reached setpoint, it just kept on cooling & cooling ... because the thermistor was still giving a false, high temp reading.

So, I bought a new thermistor, P/N 6323A20042A. My unit worked fine. Until the next week when I turned heating back on and now I have the same problem ... gives cooling but no heat. Something is failing the indoor thermistor OR the distributor sent me an old-style thermistor, I haven't gotten determination on that yet.

Regardless, call LG and see if they can't direct you to a distributor for an indoor sensor. LG's warranty coverage for parts is a royal pain, unless you can show a receipt by a certified installer, you're not going to have much luck getting payment for the part. However, the thermistor is only $10. Just hope you get one that doesn't fail on you!

There are quite a few things that could do that...
First... a bad t-stat or transformer.. is the indoor blower running???

Next, one of the limit switches has shut down the outdoor unit....that could be because of either high or low refrigerant pressure...

Fuse blown in the outdoor disconnect....

Low voltage wiring to the outdoor unit bad...

Contactor coil in the outdoor unit bad or contactor points bad....

Any of these things could cause what you are troubleshoot this you will need to be able to use an electrical meter properly and check power flow till you find the problem...

I have a Fisher& Pfridge E442B. I want to change the temperature. Problem is the temp setting panel doesn't tell u wot the temp is! There's only warmer n colder. Wot is ideal fridge temps for qld?

Cheapest way is to buy a simple thermometer and place it inside, do get an accurate one as they can vary a couple of degrees.
3C or 37F is optimum temp for a refrigerator.

Won't get hotter than 300 degrees

If you are confident that there is adequate gas in the tank to maintain combustion ... Turn off the tank valve and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the tank valve On VERY, VERY SLOWLY (I'm talking, slow motion, slow). Once the valve is fully open, light the burner farthest from the tank, first. Turn it to high and light the remaining burners the same way. This should solve your problem. Just remember to always turn the tank on VERY, VERY slowly after it has been turned off.

Also, it's a good idea to test your grill thermometer to see if, in fact it's accurate. Buy a regular oven thermometer and set it on the middle grill grate, near the front of the grill. Preheat your grill with the lid closed and when the grill thermometer reaches 300 degrees, open the hood and look at the temp on the oven thermometer. Are they the same or with in a few degrees of each other? If so, your grill thermometer is accurate. If not, it's faulty.

Personally, I always use an oven thermometer when preheating my grill, because it's more accurate. And only cost about $5.00 @ Walmart.

Hope this helps solve your problem. Please be kind enough to let me know.

Happy Grilling!!!

Oven will not achieve setpoint temperature.

You may not need anything. Most people test their oven with a dial type oven thermometer. They are slow to react and often not very accurate. When I test an oven or install a new thermostat, I use a digital thermometer with a remote temperature probe, hanging from the center of the oven, which shows the temp in tenths of a degree. I let the oven cycle on and off at least three times, then take the high and lower readings on the next cycle and average that out to see what the actual oven temp is. Most of the time, if there is a dial type thermometer in the oven it is very slow to react. After 3 to 5 cycles, they often show close to what the actual oven temp is, but the only way to know for sure is to use the more accurate digital thermometer. Most ranges with digital displays can be adjusted + or - about 35 degrees. Check your users manual for this info, but don't mess with it until you have checked the oven with a digital thermometer! Please don't bother rating this solution, as anything but a Fix-Ya drops my score. Thanks.

Oven not hot enough

the thermometer is most likely the problem, the calibratation is probably off. If you have access to a accurate digital thermometer it is relatively simple to do. If you do have one just take and set the knob to 250 degrees and when the oven gets to 255 it should go off and come back on at 245 degrees. If it's a digital there shopuld be a potentiometer that you have to adjust. good luck

I have a Vicks Thermometer, the comfort flex one, and it is not working properly. Everytime I turn it on there is a small triagle on the left side... I dont have the manual, so I dont know what that means.

Your battery is too low to allow it to operate properly, according to the manual. You can use a coin to remove the battery cover in the back to see what type of battery is needed to replace. Most drug stores like walgreens, etc, carry the watch type battery.
