Having problems with your Air Conditioners ?

I have an old 1985-86 coleman central heat and air need manual

\015 I have an old 1985-86 coleman central heat and air unit in my 4 bedroom house. I can't find the manual for it. I also need to know where the air filter is so I can change it. I just bought the house last week.\015

Answers :

The filter is located before the blower if your Coleman is in a mobile home it will be in the door facing. If it is a standard ac/heat application and a regular residential furnace the blower in the cabinet on down flow (ducts in floor) will be above it and possible in the duct connecting in the top. If its the other way (ducts in ceiling) it could be right under the blower. Either of these could have a filter cabinet on the furnace or could have a filter grille at the end of the return air duct (where the air is sucked in).

Need to change a broken blower motor in RUUD central air unit. Old central air blower motor (GE electric) was connected with brown and orange wire to 15 MHD capacitor.

Our Coleman Central heat and air unit EB20B keeps blowing the inline 3 amp fuse. How should I troubleshoot the fan relay and blower motor to look for defects that would draw too many amps. The relay and blower motor are 11 years old. Thanks Ken Rohm


The transformer is blowing the fuse because somewhere down the line two thermostat wires are shorted together. You gotta trace that out till you find the shorted wiring first. It is unlikely a component would blow that fuse. Most of the time it is wi ... Air Conditioners

We have had a coleman central air system for 5 yrs. It stopped blowing cold air into the house about a week ago. You can still here it running but no air is coming out. my husband replaced the fuses and over night it did the same thing so when my husband went to check out the unit outside he said that the line had ice on it. Is there a filter within the central air unit that needs replaced?


Ice is an indication that the refrigerant is not flashing off correctly in the evaporator coil. In most cases you can simply turn the unit off (until it completely thaws inside and out) and replace the filter. Make sure that all the vents in the hous ... Coleman Air Conditioners

Hi, i have a 9 year old rheem air and heat central home unit, my central heat runs with a 40 amp breaker. what happens is the breaker will trip after 3to 7 minuets all the time. so i just have heat for about 5 minuets.. a friend of mine we are electric contractors,, but not a/c repair. he was saying that My trouble could be my LIMIT SWITCH? let me hear from you..


A few things to ponder are as follows: Your condenser is plugged. If this is the case clean,clean,clean. I have seen this many a times. If you do not have a good air flow, you will not receive heat or cold air. Another thing to check would be the sta ... Air Conditioners

Where can I find a manual for my coleman cam II central air conditioner for a mobile home? I recently purchased the mobile home and would like to know what steps to ntake to make it work at its best. Also, I find it puzzling that the air filter is set on top of the unit inside the mobile home. It looks to my limited knowledge of central air, as if someone set the filter on top of the unit because they did'nt know the correct location placement. Can you provide any comments or advice? Thanks


Check the website for Coleman/Intertherm for a manual, you will need the model and serial numbers of the unit. The filters for these typically sit on top of the unit, some come with frames, some lay directly on the coil. If you can't find a manual on ... Coleman Air Conditioners

A miswire need schematic or some direction for adding central air to a heat only intertherm electric air handler. See the problem is when a cool call is called there isnt a problem b ut when a call for heat the blower smokes. Its clearly a miswire but scmatic set up for heat only.


The blower is smoking because you have it hooked up to the same wires you've hooked the electric coil to.  That coil runs on 240 volts.  Those wires are typically red and black.  The motor runs on 120.  One of the wires should be ... Intertherm P3RA-048K Air Conditioner

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.

One of our Fedders AEY12F7F through-wall AC/heater units has stopped heating (AC still works fine). Unit is about 4 years old. I know it has a separate heating coil (it's not a heat pump). Is there a fuse I should check first? (where?). If there isn't, or if that isn't the problem, do I assume the heater component needs replacement? If so, is this something that a skilled handyman could do? Is a manual available? If we need professional help, is someone recommended for the Portland,

Is it ok to replace outside unit of central air and heat and not the inside air handler ? The upstairs A/C( over 10 yrs old) is not keeping up with South Texas heat. The temp upstairs climbs to 84-86 degrees by the afternoon and takes 4 or more hours after dark to cool back down. I have cleaned the entire unit outside- no help. I have replaced the downstairs unit 2 yrs. ago and it works fine. I don't want to replace the upstairs air handler if I don't have to---much more cost.

I have a Coleman Evcon gas furnace model# DGAT095ADA last year I replaced the T-O-D #60T82 - 313675 fan switch and works fine. This year the unit started fine, but slowly started taking longer & longer to heat up, then finally not heating up enough to trip fan switch. Manually tripping fan switch resulted in some warm air through system, but not enough to heat a house. Gas comes on and is blue what would be my next course of action ?
