If you don't mind shopping over the internet here is a company I deal with on a daily bases Call Washer Specialties they have everything. 99% of the time.

Now if you have a appliance parts house in your area I would go there as this part you are talking about is a common part.

Goodman heat strip when t stat switched to call for heat the heat strip won't come on n it flashes on the stat calling for heat n never come on only cool air

Is this a heat package inside a Goodman air handler? If so, it is probably at least a 10kw (two element) unit and it sounds like the first stage is not coming on. Of course it could also be a 15 or 20 kw heat package with multiple heat stages, I have no way of knowing.

Sometimes the second and subsequent heating elements operate off of the 'sequencer' of the previous stage. Not always though. If its a regular furnace it should have a terminal strip with R W G Y and C on it. With the thermostat calling for heat, check for voltage (hopefully you have at least a cheap DVOM) between W and C. If 24 vac is present, find the first stage sequencer by looking at the schematic on the air handler door. Follow the wire on W1 in the diagram to the sequencer. After locating the sequencer, check for voltage across the coil....which should be the same as W and C. If there is 24vac there and it has been there for 45 seconds, the sequencer switch should be closed which then energizes the heating element. Without an 'amprobe' (clamp on ammeter) it is difficult to determine if current is flowing through the heating element.

If you can verify that the first stage element now has 240 volts across it, but there is still no heat about all you can do is turn off the power ---------- (IMPORTANT!!!!!!)-------- and remove the high voltage wire from one end of the element and use an ohmmeter (if you are lucky enough to have one) to verify that the heating element is in fact good or not. Resistance shown on the ohmmeter shows it to be good, no resistance shows it to be open and possibly the culprit.

Of course in series with the element is always a 'high temperature cut out' that could be causing the element to not heat. The same technique is used to check and verify each sequencer and element in the furnace. Its a whole lot easier if you have an amprobe.

Remember you are in a high voltage environment which is very dangerous to the untrained individual. Do not attempt this if you are nervous around electricity !!!!!

There is a whole lot more than can be written in a concise manner but this may get you in the ballpark....

OD model#, CKL36- 1F and the indoor model#, AR36-1. The indoor does not have the electric heat strip in it but has the place for it. I want to convert it to a heat pump. Is it a 3 ton system? How many KW...

You can use the existing air handler for a heat pump condenser unit up to 3 tons. The line set, evap coil are fine for a heat pump.
The electric heat strip issue can be another problem, you can put several different size strips in depending on what may be needed where you live, the power requirements will differ with each heat strip, for example a 5KW (5000 watt) heat strip requires a 2 pole 30 amp circuit for heat strip and air handler combination.

Do you have power to the unit for the new heat strips? what size strips do you have? 10kw-15kw.. ect.
If you had heat strips previously, then i will just need to know the size and application.

We have an air make up unit on our community hall with no heat

Depending on the outdoor temps, 10 kw won't heat much. If you have a multi-meter you can check the amp draw as well. You should get 20 amps for each heat strip. Each heat strip is 5kw.

I have a HVAC unit made by Inter-City Products. I

In general, when more than one heat strip is present, one is used as primary heat, and the second one comes on if the primary does not prevent the temp from falling.
Another set up is, yes there can be a time delay in the system. it usually takes a few minutes for the second set to energize.
Since you did not state if this is a heat pump, i'm limited in my response at this time.
Hope this helps.

Compatability of a R22 air handler and a R410a heat pump

1. The units should match up without a problem.
2. You will need a 40 or 50 amp breaker for the A/H and 5 KW heat strip. You will probably need a 20 or 25 Amp for the condensing unit. I would check the FLA (full load amps) rating on both units, total them and install a breaker with no more than 20% more rating than the total. You can install a small box at the A/H with a breaker for the A/H and one for the condensing unit.

Usually connected to a 30 amp & 40 amp double breaker, if it is a heat pump. 30 for cool, 40 for heat, to turn on 1 or 2 heat strips. heat strips are rated 2 5kw each.

Rheem Heat pump 5 ton heat strip 10KW what

I would say this is around 75 amps of draw at max for both the compressor and heat units. . Therefore--at least 90 amp breaker, and probably 100 amps for good measure, and at least #4 or #2 wire to the unit.
