Having problems with your Air Conditioners ?

Heater!!! Unit acts like its heating but there is no hot air. Fan turns on, heat symbol is showing on the remote, but no heat


Answers :

I am experiencing a similar problem with my Mitsubishi slimline MSH09TW unit; about 4 years old; It use to give us very hot air now it is giving some what hot air; northeastern USA current temperature about 15F. You think frigid weather in Cranbury NJ could be responsible or some thing else is going on. Please help me if you have some time and knowledge about Mitsubishi heat pumps.\015\012\015\012Sincerely, \015\012DSS
Thinking of purchasing, I browsed the mitsubishi slim web-site, and noticed they tout the A/C features. TV advertisements lead us to believe the units operate as regular ductwork heat exchangers that include a heating unit built into the exchanger. That does not seem to be the case as they suggest hooking the unit to your existing gas or electric heating unit, and also hook you up to purchase heating units.

The heat pump is not working properly. i think the problem is in the switch mechanism. when the heat is on and the thermostat is turned up it blows cold air. sometimes the compressor turns on and off. if you turn the other switch to the off position, then turn the thermostat up then turn it back to heat. it will blow hot air. if you then turn the thermostat down, wait till it turns off, then turn it back up, it will blow room temp air and sometimes the compressor will turn on.


Hi,\012The problem may be the switch, but it sounds more likely that the contactor in the outdoor unit is bad and is not making all of the time...then the compressor will not always run...\012To figure it out you will need to catch it at ... Air Conditioners

My remote controlled air conditioner would not turn off because I had dropped the remote on the floor. I tried many time to turn the air conditioner off, through the remote control, but it did not work. Finally I decided to change de alkaline batteries. They were hot!!!! Is there any risk in that? does hot mean that the battery is leaking acid? whas I exposed to mercury?

My Towerchron 2000 timer appears to be faulty. It is about 20 years old but has always worked well. The problem is - the central heating will often not come on without the hot water. In the evening when the hot water switches off, the heating turns off. I have to turn the water on again to keep the central heating on. The room thermostat is high enough (18-20C). I suspect the timer is faulty and needs replacing.

I just purchased a Totaline thermostat P47401050. I have a hot water boiler (gas) for house heat and hot water. The old thermostat had just two wires - white and red. I connected them - red to R and white to W1, but it doesn't turn the heat on. If if connect the white and red together, it does. I noticed that when I turn the thermostat up to force it to come on, "PF" appears for a second. Any ideas? Thanks!

Hi I have a Lennox heat and air conditioner roof top on my unit. What's happening is,the heat turns on for a about 10 minutes then shuts off, the only way to turn it back on is to turn off the thermostat, then turn it back on, but will keep doing the same. Oh and one other thing, the filter warning is showing on the thermostat, could it be as simple as changing the filters? Any suggestions anyone?

I turn the thermostat down at night. When I get up in the morning I turn it back up. The heat kicks on for a minute or two then the unit starts blowing colder air. If I turn the thermostat to the OFF position, wait until I hear all blowers stop, then turn it back to the ON position, it will start blowing HOT air again. Some times I have to perform this cycle 3 times to get it to keep blowing hot air. Any ideas as to what is shutting the furnace off? Thanks, Wayne

Hi, I have a Halstead combi boiler. The Central Heating works OK, but we are not getting any hot water. It cycles between luke warm for a bit and then goes cold. Not sure if it's related but occasionally the heating also stops and this is due to the water pressure having dropped. Turning the pressure back up to 1.5 bar starts the central heating again, but does still not give us any hot water.
