I have a Janitrol heat pump three zone system with a 5 ton and 2 3.5 ton units cooling 5500 sq ft. When may a/c is running it never shuts off. I just got a $843.00 electric bill for the month of May '05.
Issue is: The thermostat is set at 78 degrees, once the temp reaches 78 degrees the units will not cycle off. Runs continously. Need Help.
Could I have a stuck contactor? I did notice there were spider webs in the wiring area on the outdoors compressor unit?
Current example: Downstairs 3.5 units reached the 78 degrees at 10:38 am as of now (10:58) still running. I can manually move up the temp to 79 and system shuts off.
I have never had a electic billover $500. until this month.
Orginally I had this problem with the units 3 threes ago. unfortunally the service guy that fixed it passed away. Several service people have looked at it and they say it is fixed then once a load is put on it, it happens again.
What kind of tstats are on these units. If you set the tstat to 79 will it cycle normally? Will it shutdown when temp reaches 79?
This is a duplicated post/thread. Please stick to one thread.
I have LuxPro Tstats. No it does not cycle off when it reaches 79.
Set at 79 once t-stats show 79 is will take from 29 to 25 minutes for the units to shut off. I have a degree swing set at 2.
