It was runnig excellent untill last month I noticed that heater/indide blower was constantly running(NON STOP).I try to turn off by thermostat, but still running.Then I turnoff circuit breaker for few minutes.After I turn on circuit breaker, then it started working normal again.Untill yesterday I noticed it is constantly running(non stop) .Can any one help me to understand what is wrong in my unit??Is it thermostat?? or something else?? Shall I continue to turn off and on circuit breaker to operate it?...please help.I also called a specialist,he thinks sometimes older units does that.If I turn off the circuit breaker for few minutes and turn back on it will reprogram and would work normal.I need another openion please tell me if it is dangrous????

From what you say Id say call a tech to check it out. As the tstat didnt do anything. It can be in the board or just a
sequencer again. You dont say if its all the unit outside and in or just the inside blower. Again I think call some one to check it out for you

It could be just one of the sequencers. If the sequencer sticks and the heating element stays on it there is a device that will sense the heat and make the fan come on and stay on until it cools of or the sequencer un sticks. some times one of the sequencers will control the fan and one element. in that case it is just that the seqencer is stuck. you could try to bump it and it may stop but it does need to be replace if it is sticking.

air handler ckt board blowing fuse

curtisdsc on Feb 11, 2007

Our unit starting blowing the 5 amp fuse the on the air handler ckt board sometime Friday night and has popped it about 7 more times through Saturday night and Sunday morning. When I replace the fuse it will work fine cycling through normal operation for about 5 hours, then blow. I checked the heat pump today (Sunday) and found the main connector on its ckt board almost disconnected. After reconnecting it the system ran all day until around 8:30 when it popped again. I verified the heat pump connector was still connected and it was. Temperatures have been around 50 during the day and drop to around 35 at night. Thermostat is set at 74. The air handler is a two year Carrier model FA4BNF042010AAAA with a heater kit model MKFCEH0901N10. It is a zoned system utilizing a Bryant Zone perfect two zone controller. The zone controller indicators show normal operation and do not show any problem while operating. No wires are corroded or grounded (fuse doesn't blow when you first put it in) and all connections look good. Could the heater kit be pulling to much current? Any suggestions, other than call the repairman in the morning?

Heat Pump Nightmare!!!

I have been living in my new home for a little over a year. thisis a new home and I am the only owner. I have two (2) seperate units. A 5 ton 14 Seer heat pump (#HHP460GKC2) with Air handler and 20kw heat kit (EBP6000B) and also a 2 1/2 ton 14 seer heat pump (#HHP430AKC2) with 10KW heat kit and air handler for the loft. Can someone tell me what the temp should be coming out of the registers if it is 35 degrees outside. 5 ton heat pump is blowing out 80 to 83 and 20KW heat kit at 85 to 87. 2 1/2 ton heat pump is blowing out under 65 and inside is starting to freeze. Last night the complete 5 ton heat pump was froozen over including the outside. the whole thing looked white. Is that normal? The 2 1/2 is staying froozen on the inside and blowing could. This heat pump is not being cost effective for me. I keep the house at 70 unless we go into several days of under 25 and the I kick it down to stay on 67 and use emer to help keep it up. Last month alone I used 7500KW. That can not be right can it?
