Why is my Magic Chef electric oven not heating up?
If your Magic Chef 64HN-4TKVW-EV range powers on but the oven will not heat, the most common causes are a failed igniter, a bad temperature sensor (probe), or a wiring/connection problem. We start by confirming the igniter glows and the gas burner actually lights.
- Make sure the oven is set to Bake (not just the clock/timer) and allow 5 to 10 minutes for preheat.
- Confirm the gas supply valve is fully open and other gas appliances work normally.
- Watch the oven start sequence: you should typically hear a click, then see the igniter glow, then the burner should light.
- If the igniter glows but the burner never lights, the igniter is still a top suspect.
- If nothing happens at all (no glow, no click), focus on power, wiring, and controls.
For the Magic Chef 64HN-4TKVW-EV, these parts on our parts list are directly related to heating:
| Symptom | Most likely part | What it affects |
|---|---|---|
| No glow from igniter; no burner light | Oven igniter 12400035 | Lights the bake burner so the oven can heat |
| Oven heats but temperature is inaccurate; may shut off early | Oven probe 12001655 | Senses oven temperature for the control |
| Oven light out only (oven still heats) | Oven bulb 8009 | Lighting only, not heating |
- Igniter glows bright but no flame: replace the igniter first; weak igniters can glow but not pull enough current to open the gas valve.
- Flame lights but oven won’t reach temp: test/replace the oven probe; a drifting sensor can cause underheating.
- Intermittent heat: inspect harness connections for heat damage; repair any loose or burned terminals.
A gas oven that does not light can leave you with long preheat times, uneven baking, or no heat at all. Fixing the correct part (often the igniter or probe) restores normal bake performance and helps prevent repeat failures.

Why is my gas oven not igniting when I turn it on?
If your Magic Chef 64HN-4TKVW-EV gas oven is not igniting, the most common cause is a weak or failed oven igniter that cannot draw enough current to open the gas safety valve. Start by confirming gas supply is on, then inspect the igniter and burner area for damage or blockage.
- Make sure the range is plugged in (the igniter needs power even though the oven uses gas).
- Confirm the gas shutoff valve is fully open.
- Set the oven to Bake and listen: a working hot-surface igniter typically begins heating within 30 to 90 seconds.
- Look for glow at the igniter (if accessible); no glow often points to an igniter or wiring issue.
- If you smell gas without ignition, turn the oven off, ventilate the area, and do not keep retrying.
| Symptom | Most likely cause | What to do next |
|---|---|---|
| No glow, no heat | Failed igniter, loose wire, or control issue | Check wiring connections; replace the igniter if damaged |
| Glows but never lights | Weak igniter (common) | Replace the igniter |
| Lights sometimes, slow to light | Igniter getting weak or burner ports partially blocked | Clean burner area; replace igniter if slow persists |
| Clicking (some models) but no flame | Spark ignition issue (if equipped) or dirty burner | Clean and dry burner area thoroughly |
For this model, the part most often involved is the oven igniter 12400035. If the igniter is working correctly but the oven temperature is inaccurate or the oven shuts off early, the oven probe 12001655 can also be a factor.
A weak igniter can glow but still fail to open the gas valve, so the oven never lights or takes a long time to light. Fixing ignition problems quickly helps prevent poor baking performance and reduces the chance of repeated failed ignition attempts.

Why is the number 64HN-4TKVW-EV special?
The number 64HN-4TKVW-EV is special because it is the exact model number for your Magic Chef gas freestanding range; we use it to match the correct diagrams and replacement parts so you get components that fit and function properly.
This model number identifies a specific Magic Chef range configuration, which affects details like burner setup, oven ignition style, and which hardware fits.
Common ways we use the model number:
- Pull the correct parts breakdown for the range
- Confirm compatibility for electrical and gas-ignition components
- Match cosmetic pieces (knobs, panels) and mounting hardware
- Reduce returns caused by “looks the same” parts that do not fit
Use 64HN-4TKVW-EV anytime you are troubleshooting or ordering parts, especially for items that vary by revision.
| What you’re doing | Why the model number matters |
|---|---|
| Replacing an oven ignition part | Igniters and wiring connections can differ by model |
| Fixing an oven temperature issue | Sensor/probe styles and connectors can vary |
| Replacing a light in the oven | Bulb base and heat rating must match |
| Ordering screws or hardware | Length and thread type must match |
If you are repairing your Magic Chef 64HN-4TKVW-EV range, these are examples of parts where matching by model is important:
- Oven igniter 12400035 (oven will not heat or takes too long to ignite)
- Oven probe 12001655 (temperature seems inaccurate)
- Oven bulb 8009 (oven light out)
Ranges often share a similar look across multiple model numbers, but internal components can be different. Using 64HN-4TKVW-EV helps us keep your repair accurate, safe, and efficient.
