Hunter thermostat


Make sure that your room temperature is lower than your desired final heating temperature (or higher than your cooling temperature). Next check your wires to the thermostat. Some thermostats have screw terminals; others you push the wire into place after holding open a "lever".
A few months ago, we found that a few of the conductor wires had broken behind the thermostat. On stripping the insulation from the unbroken section of those wires and reconnecting them to the thermostat, it worked fine. There are 4-5 wires behind the thermostat, the wires that control the relays to turn on and off the heating and cooling are different from the power wires.

Next check your system. Change the filter and make sure that the door over the filter is closed. If it isn't seated, you may get a fail-safe over-riding the controls. Some newer systems will have LEDs that give trouble codes. Refer to your manual if you see any lights/code numbers. You also should check the wiring at the furnace/heat pump/AC unit. Another possibility is that the control board for the unit is damaged. (This also happened to us - a close lightning strike caused a surge that destroyed a portion of the circuit board. Your unit should have a trouble-shooting section that tells how to test the system by bypassing certain jumpers.) If the problem is at the board, call a repair person. They'll probably have the correct part on hand if you give them the make/model when you schedule the service call.
Please add a comment with information about your heating and cooling system hardware and any trouble-shooting lights, if present, for additional assistance.

Our split system is not blowing cool air all the time? Can you tell me what the problem might be. Thanks


To get proper cool, keep cool mode. Temp setting minimum 3 degree less than room temp.Check indoor coil,air filter and blower wheel are cleaned.
Check gas pressure is good by keeping your hand on suction pipe (bigger size) which gives chillness.
Hope, helpful.

My m.7732 refri has quit cooling,thr gas and electric still works, but the cooling tubes are not cold. Would the lights and displayes work if fuses were bad. They do.You can hear propane motor start up but...


COOLING Dust on the condenser coils can cause overheating, observe safety precautions then clean coils. Switch off the unit before you clean them. If the problem persists, test the compressor for overheating. Overheating will cause many problems with cooling ability. Leave the unit unplugged for 3 hours and plug it in again. If it starts working, the compressor is probably overheating (Observe cautions with food going bad). A simple cause of the problem might also be that there is not enough airflow Lack of airflow is the number one cause of compressor problems and thus an owner purchasing another unit for hundreds of dollars when you can fix it for free.There should be at least several inches distance between the sides and walls/cupboards/ceiling. Electrical There is an in-line fuse mounted in the line supplying the power to the ice-maker. It is in the wire clipped to the side, change out this fuse asap. It is actually a 20-amp fused, associated with the grounded electrical supply. PARTS You may order parts very cheap from here www.canadianappliance.ca/KBRS22KV.html TIME TO CHANGE YOUR FILTER While your on the back of the system, please check the filter. There is a filter in the back of the fridge in the upper right hand side. If you do not change it, it will slow down the frig and burn it out permanently.

I have Sumsung Washing Machine, Silver Nano, WF-B105N, 6kg, I got my drainage pump not working how to get spare part in Doha Qatar, The Error code is 5E, I alrady cleaned the filter.


the drain pump is probably fine on the other end of the filter is a drain pump lean the machine back and take the kick plate off and you will see the drain pump you need to undo three screws holding it to the filter and when you pull it apart your problem will fall out ( normally coins or bobby pins or nails if not take the hoses off as well and check/clear them save you the money and the drama.

There are a few things that need to be done, first the timing belt and waterpump if this engine has one most do, so for this you would need a waterpump timing belt kit with pulleys, next is a complete tune up, spark plugs ,wire if eng uses if not then coil boots, air and fuel filters cabin filter, pcv valve, a fuel system cleaning which is done by machine at a shop called a motor vac service. then check fan belt , flush cooling system, coolant needed.and then the rest of the service is a lot of checking like brake, suspension , exhaust etc,hope this helps.
