Sounds like bad cold control. Replace it. I cannot see your repyl due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

if you claim that your heater core is flushed properly then my bet is the temp regulator is bad.

SOURCE: Heat pump cycling on and off.

It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.

E5 Outdoor activation of compressor over heatprotection or motor lock
Check condenser coil. If dust blocked-clean it.
Check out door fan motor is working. If not replace capacitor or motor.
Check compressor-gradually amps increasing-replace capacitor.
Check for gas pressure. No gas also gives over heat compressor.- Leak test and rectify.

What does external protection devices activated mean? ( EO code)


these are saftey swithes that are used say if your out door unit fan quits the compressor will run hot and shut off or if your indoor unit is stoped up the unit will run low pressure wich will shut off by the low pressure switch usually if its dirty or low on freon it will come on and off three times or so and will shut its self off.

Heater doesn't heat when cold


Chances are it is indeed the heater core as even a spent heater unit will blow hot air off the engine when the ambient temps are hot . When the temps drop, the heat from the engine block is not enough to heat the cab properly. Have you tried the old cardboard in front of the radiator trick? Speaking of semi's,ever notice they cover their radiators in the winter? That's because it helps get their block temps up a little higher and assists with heating as well. It's not much help but do the buyer a favour and let them know beforehand. Have a good one. :)

My 2004 e270's second battery "died" and was replaced. How I realized this was the aircon went into "off-mode". The AC is now working again but not at the same chill as before.


For an ac to work there has to be heat in the cab to evaporate the gas after it leaves the TX valve . Check that if the ambient air temp is well down then the ac temp may not be as good as it could be expected on a hot day. Check that the ac clutch is engaging and you are not reading ambient temperature through the system

I have a GrandAire and the aircon works fine; when I turned the heat on, it seems to work fine (warms the house), but the fan in the outside unit is not spinning when the heat is on...is this a problem?...


I think your unit is working in good condition. If you keep in cool mode the out door fan runs to condensate the heat in condenser by taking fresh air from the ambient. And when you keep heat mode, definitely the ambient temp will be too less.I fit takes from their then compressor will get frozting and it couldn't work properly. Depending on pressure increase, the fan will automatically run and stop. Don't worry. Thanks.

I have a Goodman condensing unit that freezes up occasionally during low ambient weather (20 F). Model # ssz160361ac with matching new air handler. I have adjusted the defrost time from 90 to 30min. This...


It is not freezing up because of the temperature, but because of ice being formed in inside. Either by a blocked condensation duct, or snow due to previous storm.

Heater blows out lukewarm heat after car is warmed up


Does temperature of heat increase at all, when RPM's of engine increase?
Cool when idling, warmer when engine is revved a bit?

Airconditioner LG LSk181-N2 shutting off


Sounds like your aircon is stuck on heating mode. Or. The outdoor fan speed is affected by ambient temperature, or low refrigerant. In heating mode the indoor fan will come on for a while to sense temperature and will then wait for the outdoor unit to pump up pressure and build up heat.

Appliaance shuts off at low temperatures


Most refrigerators cycle on and off based on the fresh foods temp. If the ambient temp is 10C and you have it set for 4C, the unit does not have to run much to satisfy the temperature control, and the temp in the freezer section will warm to + C range. (likewise, if the ambient drops to -C range, it won't mater if you set the fresh food section to +4C, it won't heat the air, and the fresh food section will eventually reach the -C ambient temp.) The only solution is to move the appliance to a warmer location or heat the room it is in. This is the only Fix-Ya for your refrigerator.
